Rethink how to implement pause (_) between event sequences

[jschepers]

Currently, when using _ in the end of a sequence, there will be a 2*maxlength(components) distance between the sequence repetitions to avoid overlap.
However, after the introduction of component offsets, that no longer holds true and there might be overlap depending on the choice for offset.

Suggestion: Also add maximum(abs(offsets))
