Investigate handling of negative CQL `duration` values, handling #1647

Apparently (see f.ex https://docs.datastax.com/en/drivers/java/4.4/com/datastax/oss/driver/api/core/data/CqlDuration.html) CQL CqlDuration values can be negative. This is not something ISO-8601 supports it seems (https://en.wikipedia.org/wiki/ISO_8601#Durations).

So, need to investigate how handling works, if users insert negative duration values via CQL (or Data API using C* duration syntax), what should we do on output path?

  1. Throw an exception for invalid value (Codec failing)?
  2. Product special value to indicate issue?

or something else?

Looks like CqlDuration accepts leading - for its own "compact"/"standard" format AND ISO-8601 (non-standard but whatever), so it may be quite simple to support such values.
