Tempo.MaterialisationError exception (Tempo v0.20.0)

Exception raised when a value cannot be materialised into an explicit Tempo.Interval or Tempo.IntervalSet.

Reasons include a bare Tempo.Duration (no time-line anchor), a one-of Tempo.Set (epistemic disjunction, not an interval list), a Tempo already at its finest resolution (no finer unit to bound the implicit span), and an unanchored group (e.g. 5G10DU — days 41..50 with no year/month to bound the span).
