[pvizeli]

use a set instead a list, that is faster

[aequitas]

For lists this size there is no significant difference as far as I can measure.

Ok to merge when @aequitas has tested it 👍

Still waiting for feedback from DSMR5 testers.

One user reported in and current implementation does not work. Waiting for debug output. Will create new PR for additional changes. Assumption is this change does not break anything for non DSMR5 users so should be safe to keep merged.
