[mod] Throw on invalid compile-time min-level

This is technically a breaking change.

Before this commit:

  If an invalid compile-time min-level was provided, it would be
  silently ignored.

  User would need to specifically check their *config* :compile-time-config
  value to see that something went wrong.

After this commit:

  If an invalid compile-time min-level is provided, immediately throw.
  This'd happen at compile-time.

Motivation:

  The previous behaviour made it easy to miss an invalid
  compile-time min-level.

  While the change introduced here is technically breaking, it would
  break ONLY those users with an invalid min-level - and it'd break
  them only at compile-time.

  So this should hopefully be a welcome change if documented clearly.
