b5abd2bff1 Lexer rewrite:
- Scan the input string *linearly*, without backtracking
  - Peek at most one character (unicode code-point) ahead
- Store data (unescaped string literals and chars, identifiers, integers, floats) inside Token
  - This unfortunately makes tokens non-Copy
- Refactor Parser to accommodate these changes
  - On the bright side, Parser no longer needs a reference to the text!
- Write a new set of lexer tests
  - TODO: write a new set of token tests using tokendata

Every day, we get closer to parsing `dummy.cl`!

097e2c4f11 conlang: Rename literals; split, compose, and document Rules
- Renamed literal Types to reflect their literal nature
  - This allows for consistent naming across future non-literal Types
- Complicated lexer Rules have been split into composable sub-rules,
  and moved into the Rule struct.
  - This improves modularity, and allows sharing of sub-rules across rules.
- Documented each lexer rule with (at least) a one-line blurb
  describing its function
