fix(protocols): PCAP-NG timestamps outside Windows' fromtimestamp range render as 1970 #2099
Description
Job 120605026883, the first Windows run of #2095's leg: test_pcapng_tzone_tsoffset_range_1340_unit::test_tsoffset_in_range_is_unchanged fails for -62135510400 and 253402214399 with PCAP-NG: [Block 6] invalid timestamp, and the frame is dated 1970.
Inferred (the log does not show which exception): Windows' datetime.fromtimestamp(..., tzone) cannot handle these in-range year-1 and year-9999 epochs, so the fallback fires.
Proposed: compute datetime(1970, 1, 1, tzinfo=utc) + timedelta(seconds=…) and then .astimezone(tzone), which does not depend on the C runtime. This is a #2060 phase-2 prerequisite.
