feat(rawcli): INVENTORY_READ / FAST_INVENTORY_READ for the SLIX catalogs

Browse Source 
Completes the ICODE SLIX/SLIX2 datasheet command set. These fuse an inventory round
with a block read; unlike every other catalog command they need the inventory bit set
in the request flags. Added an `inventory=` option to iso15_frame (sets inventory +
single-slot, 0x26 with high rate) and both commands to _SLIX (inherited by _SLIX2),
with the mask-less body mask_len 0 | first_block | count-1 (matching the tag model's
_handle_inventory_read: first_block at data[4], num_blocks at data[5]+1).

Verified live (completer names both, opcode 0xA0/0xA1 map back, entry round-trips) and
unit-tested. Mask-based inventory (AFI/mask value) left as a future refinement.
