0d3980d039 Refactor how map file sections are printed 
This makes size-0 sections print as "($0000 bytes)" instead of
"(0 bytes)", which is more consistent.

57c3d74b9e 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

e548ecc6fa Report attempts to assign a SDCC area in a way inconsistent with its data 
This actually avoids breaking the (segfaulting) invariant that
a section whose type "has data" has as many bytes of `->data` as
its `->size`.

00b0914436 Reserve space to avoid file sym array realloc 
This line was missing; in its absence, as soon as the array reallocs,
all registered symbol pointers are invalidated, leading to a crash
(e.g. when generating a sym file).

Made the reallocation check into a hard error, too.
Since fileSymbols gets registered with each section, we would have to
change that, and then it cascades throughout all of RGBLINK.
This will be handled correctly in the Rust port.

379aa8c267 Use line.reserve in sdobj_ReadFile instead of constructor 
Passing a count parameter to the vector constructor does not reserve
count elements but instead fills the vector with count elements.
This caused the endianness check to fail first because the first 256
characters were null bytes.

2706f94788 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.
