hf.mfc renamed to hf.mf to match the C client's 'hf mf'. New hf.mfu (HFMFUCommands) provides rdbl/wrbl/dump over the dedicated CMD_HF_MIFAREU_READBL/WRITEBL using the firmware mful_readblock_t / mful_writeblock_t structs; a READ returns 4 pages (16 bytes) and the firmware replies them directly. keytype selects auth (0=none, 1=UL-C, 2=EV1/NTAG pwd, 3=UL-AES). Wire formats verified against firmware structs; needs a bench pass for the auth/write-length paths.

Phase 1 of package refactor. Moves all source modules into pm3py/core/
with file renames (hf_14a→hf_iso14a, hf_15→hf_iso15, hf_mf→hf_mfc)
and client attribute normalization (hf.a14→hf.iso14a, hf.mf→hf.mfc).
pm3py/__init__.py re-exports from core for backward compat.
