Use a custom generic tagged union Either instead of std::variant for efficiency ( #1476 )
...
* Implement custom generic tagged union `Either`
This should be more efficient than `std::variant`, while still
keeping runtime safety as it `assert`s when `get`ting values.
* Use `Either` for RPN expressions
* Use `Either` for file stack node data
* Use `Either` for `File` buffer
* Use `Either` for `STRFMT` args
* Use `Either` for RGBLINK symbol values
* Support an equivalent of `std::monostate` for `Either`
* Use `Either` for lexer tokens
* Use `Either` for symbol values
* Use `Either` for lexer mmap/buffer state

Multiple fixes and enhancements to RPN behavior: ( #1448 )
...
- FIX: `Label & const` was not actually doing the `& const` masking
(fixes #1446 )
- ADD: `LOW(Label)` can be constant if `Label` is aligned to 8 or more bits
(resolves #1444 )
- ADD: `!expr` can be constant 0 if `expr` has any non-zero bits
(resolves #1447 )
- `LOW()` and `HIGH()` have their own RPN operator values
(resolves #1445 )
The change to RPN values means that the object file version was incremented.
This also refactors unary operators and functions, combining their
evaluation similarly to binary ones.

Use a smaller size for the lexer buffer
...
Large sizes are more efficient when it's actually buffered,
but most of the time `mmap` is used instead, and the extra size
just slows down allocation of lexer states.

Fix two bugs with RGBASM fixed-point math ( #1388 )
...
- Fixed-point formulas are implemented using IEEE-754 floating-point
internally, which could give infinity or NaN values whose conversion
to fixed-point integer was platform-dependent.
- Formatting fixed-point $8000_0000 (INT32_MIN, -2147483648) was
not putting the negative sign in front.
