* src/paca.mjs
(escapingStateStep): Return an error when escaping non-metacharacters.
This way cases like \d, which is syntax for [0-9] which will
eventually be recognized, will not change its behaviour from a noop
escape of "d" to matching digits.
(operatorChars, isOperator): Hoist both of these up before their usage
in `escapingStateStep()`.
* tests/paca.mjs
(test_isOperator): Hoist its definition and position inside the
`runTests([...])` array to match src/paca.mjs.
(test_escapingStateStep): Adjust existing cases and add test case for
good/bad escapes.
(test_tokenizeRegexStep): Fix bad starting escape, that broke because
it was escaping a non-metacharacter.

* src/paca.mjs
(isTransition): Add new function as an improved version of the raw
usage of `stateTransitionOperators`, equivalent to `isAnchor()` and
`isOperator()`.
(operatorChars, isOperator): Add new static set `operatorChars` as
backing data of `isOperator()`, instead of ad-hoc conditional in its
implementation. Also now add the `.` character as an operator by
including it in the `operatorChars` set.
(tokenizeRegexStep): Use the new `isTransition()` function instead of
checking the set directly. Also tweak ternary to fit in 80 columns.
(PRECEDENCE): Add `.` operator with lowest precedence, as it is not
really operating on anything, and is instead a target to be operated
on.
* tests/paca.mjs
(test_isTransition): Add obligatory test cases.
(test_isOperator): Include test case for `.` wildcard operator.

* src/paca.mjs
(ANCHOR_FNS): Add simple handlers for ^ and $ anchors, that only look
for the position of the character in the pattern as validation
during tokenization.
(isAnchor): Add simple boolean function to identify anchor characters.
(tokenizeRegexStep): Include check if character `isAnchor()`, and call
the appropriate `ANCHOR_FNS[char]` when true.
* tests/paca.mjs
(test_ANCHOR_FNS): Add test with 4 cases - 2 for success and 2 for
errors for ^ and $.
(test_isAnchor): Add obligatory simple test cases.
(test_tokenizeRegexStep): Include test case for tokenizing patterns
with character class.

* src/paca.mjs
(escapingStateStep): Use `shouldConcat()` instead of only checking if
we're on the last char. We abuse it a bit by passing `null` as the
first argument, since it is being escaped.
(nonConcatOperators, shouldConcat): Hoist the definition of both above
`escapingStateStep()`, so that they're defined before being used.
* tests/paca.mjs (test_shouldConcat): Add test case where `null` is
explicitly passed as the first argument.

* src/paca.mjs (classStateStep): New function equivalent to
`rangeStateStep()` for character class expressions. For now it knowns
how to handle escaping ([abc\-_]), simple ranges ([a-z]), negation
([^abc]) and the hyphen literal as the first char ([-a-z_]).
* tests.paca.mjs (test_classStateStep): New test entry has a test case
each scenario described above.

* tests/paca.mjs (test_rangeStateStep): Add first test case, for when we
find a closing "}" when no comma was seen.

* src/paca.mjs (numFromDigits): Move it to before the *StateStep
functions, as it is now used in `rangeStateStep()` function. So
instead of letting it be defined afters its usage, move it up.
* tests/paca.mjs: Do the same hoisting to the import of the
`numFromDigits` name, to the definition of `test_numFromDigits` and
its inclusion in the order of the call to `runTests()`.

Introducing "[" now we will start to write the code to parse the
character class expressions, i.e. [a-z0-9]. The `context` key will
contain a `set` with all the literal characters that were found, and all
the ranges too. For parsing the ranges, a `range` key equivalent to the
one for the {m,n} range is used. Despite the superficial syntax being
simmilar, its logic, semantic and implementation will be different.
* src/paca.mjs (TRANSITION_FNS) <"[">: Add new transition function for
handling the start of a character class expression.
* tests/paca.mjs (TRANSITION_FNS): Add a singular test entry, that
exercises the conditionless body of the function.

* src/paca.mjs (TRANSITION_FNS): Add trailing underscore to ignored
arguments, even though it breaks the name of the `_state` and
`context` destructuring arguments.
* tests/paca.mjs (test_TRANSITION_FNS): Add new test function with a
single case for each transition character. Since these transitions
are unconditional and contain no logic, this single sample test is
enough to cover for all of its behaviour.
