Abdessamad Derraz 11da070128 chore: recale the profile refs onto their pins
Upstream moved under 145 profiles: 679 refs shifted and 452 followed a
renamed file, against 6,483 that still anchor where they were written.
The recale rewrites the located ranges only, keeping the annotations and
the sentences that carry them, and 106 pins advance in the same commit
because refs and source_commit name one revision or the profile
describes two at once.

Nothing here was guessed. The 183 refs that are CHANGED, GONE or
AMBIGUOUS are untouched, and the 57 profiles holding them keep their old
pin until someone reads the diff: profile_sync refuses to recale a
profile while any of its refs needs a re-read. trident kept its pin too,
its annotated ref being one the writer will not rewrite.

notes: >
High-accuracy SNES/SFC emulator with Game Boy/Color and Super Game Boy
support. Upstream archived at 0.4.0, superseded by Mesen2. DSP firmware
can be loaded as combined files (dsp1.rom, dsp1b.rom, dsp2.rom, dsp3.rom,
dsp4.rom, st010.rom, st011.rom) or split program/data ROMs. Combined
files are tried first, size validated. HLE coprocessor option available
for DSP-1/DSP-1B only (libretro core option mesen-s_hle_coprocessor).
CX4 is fully HLE, no firmware needed. ST018 detected but not emulated.
GB/GBC/SGB boot ROMs fall back to embedded open-source SameBoy boot ROMs
when external files are not found.
