cc59730c5b Cleanup the RPN evaluator somewhat 
Make the bool field an actual bool
Rename `iReloc` to a more exact `isKnown` (as was already pointed out by some
comments)

af6f62701c Remove ambiguous charmap syntax 
The syntax was `charmap "anything", "string"`; the second string was
already handled by `const`, but to the same effect... the ambiguous
declaration has been removed, leaving us at "only" two reduce/reduce
conflicts.

This was made separate with the intention of supporting multiple versions,
but after some discussion this was decided against, so better improve

f2be601a13 Check "left" boundary as well in isLocationSuitable 
"fixed" and "aligned" location checking advanced the target location to places
regardless of the associated free space, potentially breaking the assumption
that the location was always further in memory than the free space's base.

Rather than adding more code to try keeping that assumption true, harden
`isLocationSuitable` and handle that case as well.

b16ec83a33 Add gbdiff.bash script 
This script allows diffing two Game Boy ROMs using `xxd` and `diff` and
attempts to augment the diff using information pulled from SYM files.
It's not part of RGBDS proper, but can be useful to debug tests (when ROMs fail
to match).

93ee417567 Fix timestamp symbols on Windows (partially) 
Windows does not honor `%F` nor `%T` in `strftime`. These are worked around
by writing the full format they serve as a short for.
However, Windows also treats `%z` and `%Z` identically, where SUS instead
requires `%z` to output a ±XXXX offset.
Since the current information is broken (no information), this isn't *breaking*
anything, but at least provides something a human will probably understand.
`__ISO_8601_UTC__` is unaffected because it hardcodes the timezone character,
only `__ISO_8601_LOCAL__` suffers from this.
