Adds a spec-verified FCP/FCI decoder (ISO 7816-4 5.3.3 Tables 12-14,
TS 102 221 11.1.1.4; cross-checked against pySim ts_102_221.py — spec wins
on the data coding byte and termination mask). fcpDecode accepts the FCP
template '62', an FCI '6F' wrapper and bare FCP content, and decodes:
file size/total size, file descriptor (access/shareable, file type,
structure incl. BER-TLV/SIMPLE-TLV, data coding byte, record length/count),
FID, DF name, SFI, life cycle status, security attributes, the A5
proprietary sub-DOs (UICC characteristics, power, clock, memory, file
details, sizes, commands, environmental conditions, test config) and the C6
PIN status template DO. Unknown TLVs are preserved raw.
Usage:
- check report: an 'Exact FCI' mismatch now renders a decoded
expected/actual table under the raw fields, highlighting differing
parameters and showing missing ones as '—'
- rule editor: the FCI hex textarea shows a live decoded FCP preview
10 new tests (vectors incl. pySim linear-fixed, malformed inputs, diff
highlighting, report integration). Help docs updated. SW cache v71 -> v72.
