feat(mux): count the TR 101 290 errors of a TS feed at import

+`import ts` also counts the ETSI TR 101 290 errors of the feed it receives, at
+that standard's fixed limits: `TS_sync_loss`, `Sync_byte_error`, `PAT_error`,
+`Continuity_count_error`, `PMT_error`, `Transport_error`, `CRC_error` (PAT and
+PMT), `PCR_repetition_error`, `PCR_discontinuity_indicator_error` and
+`PTS_error`. They are cumulative, logged with their totals in the sample after
+any of them moves, and carried on `Import::stats` stream-wide and per PID. They
+change nothing that is published. They grade the stream as it reached the
+importer, not the wire a receiver sees downstream, and the PCR checks grade
+consecutive PCR values rather than arrival times, so they speak for the encoder
+and not for the network in front of the importer. Table, PCR and PTS intervals
+run on the program clock, which starts at the first PCR after the PMT.
+`PID_error` is covered, more strictly, by the access-unit counts above.
+`PCR_accuracy_error` is not measured.
+
 MPEG-TS import takes one program. A multi-program stream is refused before
 anything is published, naming its programs, rather than merged onto one clock;
 a PAT that adds a program mid-stream ends the import the same way.
