feat(rawcli): full INVENTORY_READ request body (mask + AFI) — 15693 complete

Browse Source 
_inv_read_frame builds the complete ICODE inventory-read request body:
[AFI] | mask_len(bits) | mask value | first_block | count-1. INVENTORY_READ and
FAST_INVENTORY_READ gain optional mask_len/mask (selective anticollision, ceil(bits/8)
value bytes) and afi (filter byte + the 0x10 inventory flag, flags -> 0x36). Mask-less
stays the default, so existing frames are unchanged.

With this the ISO 15693 support is datasheet-complete end to end: the full request-flags
byte, both SLIX and SLIX2 command sets, and the inventory-read body. Verified live
(mask-less / 16-bit mask / AFI forms build + decode + round-trip) and unit-tested.
