em_mrc_read — FILEIO `mrc` op

• Data kinds: any → any

• Call: import fullseye as fs; fs.ledger.em_mrc_read(data) (to call the implementation directly, import fileio; fileio.em_mrc_read(data); from the registry, opsfileio.get("em_mrc_read"))

• GPU: none (CPU reference implementation only)

Usage

Read MRC2014/CCP4 mode 0/1/2/6 as (image_or_volume, meta).

meta は Å 単位を明示した voxel_size / origin を返す。非標準軸順、extended header、切れたデータ、shape と mode の不一致は名指しで拒否する。

呼び出し例: volume, meta = em_mrc_read(payload)。
