Map the French, German, Italian and Spanish releases' addresses (#84)

PRET builds none of these releases, so scripts/map-revision.mjs derives
where each keeps the profile's labels from the 1.1 build: a bank-by-bank
alignment, then the exact references RGBDS recorded while linking 1.1,
read at the matching place in the release, each result checked against
its bytes. All but 1-3 labels per release are found; the rest, in code the
release changed, are -1 so reading them refuses. check:reference verifies
the generated file when the ROMs are present.

CrystalAssets now points the profile at the cartridge's addresses, and
the releases' characters (from their own fonts) and two European text
codes decode. The introduction and Mom's scene play in each language and
every map sweeps as in English, but the releases stay refused until the
logic they localize (units, word order, layouts) is ported.
