Make Parse take raw NFC UID and 1K image.

Drop zip/JSON from the root API. dump remains an adapter for the Android app format; inventory and an AMS wand both call Parse(uid, image).

-Go library for Bambu Lab filament NFC dumps produced by the Filament NFC dump Android app.
+Go library for Bambu Lab filament NFC. Input is **raw NFC**: chip UID bytes and the 1024-byte MIFARE Classic 1K image — not a phone dump format.
 
 ```go
 import bambunfc "git.s1d3sw1ped.com/s1d3sw1ped/bambu-nfc"
 
-tags, err := bambunfc.ParseZip(r)
+tag, err := bambunfc.Parse(uid, image) // uid from ISO 14443, image is 1K
+keys, err := bambunfc.KeysA(uid)       // 16 Key-A values to dump the tag
 spools, err := bambunfc.Merge(tags)
-keys, err := bambunfc.KeysA(uid)
 ```
 
-- `dump` — brand-blind `filanfc-dump/v1` JSON/zip
+`dump` can still decode the Android app's `filanfc-dump/v1` zip if you need that adapter; the inventory site should call `Parse` with UID + image (phone, AMS wand, or anything else).
