Every other translation unit in BIDSLIB derives its allowed values from the constants defined here, so a future BIDS specification bump (currently 1.9.x) only requires touching this header. The file groups five orthogonal concerns: BIDS datatype strings (meg, eeg, ieeg, anat, …), per-modality raw-data file extension whitelists, bidirectional FIFF-kind ↔ BIDS channel-type maps used by BidsChannel and BidsRawData, coordinate-system name ↔ FIFFV_COORD_* maps used by BidsCoordinateSystem, and the canonical entity order (sub, ses, task, acq, run, …) consumed by BIDSPath when it serialises a filename.

Header-only and inline so the maps are constant-folded at the call sites and to avoid a hidden ODR surface for translation units that only need one or two entries.
