Vendored 5 packages from iOpenPod (TheRealSavi/iOpenPod): iTunesDB_Writer/ — binary iTunesDB generation iTunesDB_Shared/ — field defs, constants, album identity SQLiteDB_Writer/ — SQLite databases for Nano 6G/7G iTunesDB_Parser/ — play stats reading from iPod ipod_device/ — device detection, FireWire ID, capabilities Rationale: iOpenPod is a standalone iPod manager app, not a library. Pulling it as a pip dependency is heavy and confusing for users. Changes: + src/vendor/ — 77 .py files + calcHashAB.wasm (506 KB) ~ ipod_nano7_db.py — _find_iop_root() now returns src/vendor/ ~ requirements.txt — iopenpod replaced with wasmtime + pycryptodome ~ .gitignore — removed iOpenPod/ exclusion (setup.py reads requirements.txt automatically)

"""MHII (Artist Item) parser for iTunesDB.
|
|
|
|
Each MHII lives inside an MHLI (artist list, MHSD type 8) and contains
|
|
artist-level metadata (artist_id, SQL ID) plus MHOD type-300 children
|
|
with the artist name string.
|
|
|
|
NOTE: This chunk shares the ``mhii`` magic with ArtworkDB image items,
|
|
but in the iTunesDB context it represents an artist record.
