Hoist `numFromDigits()` before its usage

* 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()`.
