/**
 * RFC 1982 serial-number arithmetic for the 32-bit MMTP AL-FEC symbol
 * counters (ISO/IEC 23008-1:2023 C.5.2 SS_ID, C.5.3 SS_Start).
 *
 * SS_ID is a 32-bit field, so a stream that runs long enough wraps it to 0.
 * Ordering two SS_IDs (or two blocks by their first SS_ID) with `<` reads
 * every post-wrap value as older than every pre-wrap one. Serial order
 * agrees with `<` whenever the two values are less than 2^31 apart, so for
 * every stream that has not reached the wrap the result is unchanged; only
 * the order across the wrap point differs (BLO-35597 iso:5).
