feat: 1.4.5 Update logic to save/load RNG advancements, seeded runs, bump deps

[jgabaut]

Added

• Add logic to save/load the RNG state across runs
  • Updates #80
• Add hlpd_rand(), G_RNG_ADVANCEMENTS, gen_random_seed(), hlpd_hash()
• Add is_seeded to Gamestate to handle seeded runs
  • Seeded runs are started with -S <seed>
• Add G_RNG_ADVANCEMENTS value reset section to prep_Gamestate()
• Add -D to use current dir for saves
• Add proof-of-concept binary tool for savefile handling

Changed

• Randomly generated seeds are now strings between 8 and 19 chars long
• Drop src/utils/bin_saves.h
• Drop is_localexe from Gamestate
  • To use current directory for saves/files, run with -D
• Bump amboso to 2.0.6
• Bump invil to 0.2.12
• Bump koliseo to 0.4.2
• Upgraded helapordo.doxyfile for doxygen 1.10

Fixed

• Fix cases where loading/saving an Equip could fail because its perksCount was == EQUIPPERKSMAX
  • Closes #79
  • May need further inspection... Seems good
• Fix cases where loading a zero-initialised Room led to failed enemy index read
  • ser_Room() sets class as BASIC when passed Room is NULL, rather than letting 0 be used for the class field
• Fix: move enemyTotal randomisation call in initRoom() into the ENEMIES class case
• Fix: updateSelectedSpecialW() iteration index
  • Closes #81
• Fix: avoid restarting colors, window box in draw_floor_view()
• Fix: partial fixes to errors for missing save directories
  • By default, the game will try to use the global directory. The goal is not to fail if any needed directory is missing, as long as we can create it ourselves.
  • Skip prep of save.txt with G_EXPERIMENTAL_ON == 1
