May the 4th be with you! ⭐ 👾

Added

• New 0-indexed string functions (we plan to eventually deprecate the old 1-indexed ones):
  • STRFIND and STRRFIND: like STRIN and STRRIN
  • STRCHAR: like CHARSUB
  • STRSLICE: like STRSUB, but taking start and stop indexes, instead of a start position and length
• CHARCMP: compares two strings by their charmap value sequences
• CHARSIZE: counts how many charmap values a single character would map to
• REVCHAR: reverse-maps a value sequence to its charmap string (the values must have one unique corresponding charmap)
• Allow macro \<arg> to take negative values to count arguments from the end (e.g. \<-2> is the penultimate arg)
• Allow the index of bit/res/set instructions to be determined at link time
• rgbgfx -B/--background specifies a "background" color; tiles entirely of that color will be skipped in the graphic output
• rgbfix -o/--output can write its output to a different file than its input (must have one input file); thanks @jmillikin!

Changed

• Raw symbols do not undergo EQUS expansion (so #symbol can be used instead of "{symbol}")
• Some invalid instructions have more specific error messages than just "syntax error"
• Terser RGBASM output for sequences of unknown characters
• contrib/gbdiff.bash does not need a .sym file to be sorted

Fixed

• Macro names could be used as numeric symbols with value 0
• Map files were listing anonymous labels (as Unicode escape syntax)
• RGBGFX could segfault with transparent colors in embedded palettes
• RGBGFX could segfault or give incorrect output for grayscale images with transparent colors
• RGBFIX expects nonzero -r/--ram-size for -m MBC6 (the one game that uses MBC6 has -r 3)
• CMAKE_CXX_FLAGS_DEBUG can be user-specified

Thanks to @Rangi42 and @ISSOtm for the work done for this release.
