/**
 * Parses an NMEA 0183 v4 tag block wrapping a sentence.
 *
 * Input example:
 *   `\\s:compass,c:1438489697*13\\$IIDBT,035.53,f,010.83,M,005.85,F*23`
 * Output:
 *   { sentence: '$IIDBT,...', tags: { source: 'compass', timestamp: '2015-08-02T...' } }
 *
 * Returns `false` when no tag block is present so callers can fall back to
 * default tags without a separate `null` vs `undefined` split.
