Change fields of tokens, results of lexical analysis, as follows:
- Rename: mode -> mode_id
- Rename: kind_id -> mode_kind_id
- Add: kind_id
The kind ID is unique across all modes, but the mode kind ID is unique only within a mode.
Change fields of a transition table as follows:
- Rename: initial_mode -> initial_mode_id
- Rename: modes -> mode_names
- Rename: kinds -> kind_names
- Rename: specs[].kinds -> specs[].kind_names
- Rename: specs[].dfa.initial_state -> specs[].dfa.initial_state_id
Change public types defined in the spec package as follows:
- Rename: LexModeNum -> LexModeID
- Rename: LexKind -> LexKindName
- Add: LexKindID
- Add: StateID

A fragment entry is defined by an entry whose `fragment` field is `true`, and is referenced by a fragment expression (`\f{...}`).

lex mode is a feature that separates transition tables per each mode.
The lexer starts from an initial state indicated by `initial_state` field and
transitions between modes according to `push` and `pop` fields.
The initial state will always be `default`.
Currently, maleeni doesn't provide the ability to change the initial state.
You can specify the modes of each lex entry using `modes` field.
When the mode isn't indicated explicitly, the entries have `default` mode.

APIs of compiler and driver packages use these types. Because CompiledLexSpec struct a lexer takes has kind names of lexical specification entries, the lexer sets them to tokens.
