Penalty time parsing from external data source in new draft spec

[Kevinjil]

The CDS already implements the new draft spec, and exposes the penalty time as a relative time string instead of an integer in seconds.

We probably want to create a new DTO event version for the new spec with the changed parsing. A temporary fix has been pushed to fix/penaltytime

[Kevinjil]

Note for everyone that uses a data source with the new draft spec: fix/penaltytime has been rebased after merging #2969, such that is can easily be cherry-picked on top of main again.

After icpctools/icpctools@8803bab we can make that DTO now.
