- Split the PPS exchange into the two standard GSMTAP-SIM subtypes:
0x02 (PPS_REQ, raw request bytes, span ss..es_req) and 0x03 (PPS_RSP,
raw response bytes, span es_req..end), replacing the single 0x02 packet
with concatenated request+response that deviated from libosmocore's
gsmtap.h. Wireshark now dissects both halves; simtrace2-pysniff needs
no change (its importer already maps 0x03 to 'pps' and _decode_pps()
parses the 0xFF-leading response frame). PPS annotation/log unchanged.
- gsmtap_stream.py: GSMTAP_SIM_PPS_REQ/RSP constants; header field labels
aligned with libosmocore's struct (signal_dbm/snr_db).
- Docs: GSMTAP event tables (EN/RU) updated, PPS deviation note removed;
corrected the res-byte flag attribution -- upstream simtrace2 never
sets res, so the GSMTAP_FLAG_BAD_FCS carriage is this decoder's own
extension (semantics mirror simtrace2's USB data flags).
- Tests: assert the PPS subtype values; baseline regenerated (only the
version line and test listing differed -- no decode-metric changes).
68/68 unit tests.
