fix: bring crameri up to spec with v8

[tlambert03]

continuing with #141 ... this brings crameri to complete parity with the current v8 data on zenodo. and adds a parity test:

• Regenerates the four tables SCM 8 revised but didn't reverse (tokyo 56/255, acton 34, bamako 20, batlowK 14)
• re-cuts the five maps from feat: update for crameri v8 #83 that were stored at 5 decimals instead of 6, and repoints the remaining __source__ pins to the 8.0.1 deposit (zenodo 8409685) — those tables are byte-identical in both deposits, so that part is metadata only.

All 40 crameri maps are now bit-exact against SCM 8.0.1. Adds
test_crameri_data_parity (oracle: cmcrameri 1.10, which vendors the same
deposit) so this can't drift again.
