14a.sim sent a MIX frame but the handler is NG casting a packed {tagtype,u16 flags,uid[10],exitAfter,rats[20],ulauth...} struct -> whole struct garbled, flags never arrived. Rewrite to send_ng with the exact struct and expose tagtype (2=Ultralight,7=NTAG) so Ultralight/NTAG sim works. 14a.sniff sent MIX (args stripped -> empty asBytes); send NG with the 1-byte param. Pre-existing, independent of rebase.

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.
