Collection metadata merging: support eo:bands summaries

[soxofaan]

common issue in https://github.com/openEOPlatform/architecture-docs/issues/288 :

(stac_summaries.py:142): Unhandled merging of StacSummaries for summary_name: 'eo:bands'

support for eo:bands is quite important (e.g. for band metadata support in python client)

[JeroenVerstraelen]

Note that it is handled on this line:
https://github.com/Open-EO/openeo-aggregator/blob/master/src/openeo_aggregator/metadata/models/stac_summaries.py#L143

We currently only handle merging of these StacSummaries:

• "constellation"
• "platform"
• "instruments"
• summary starting with "sar:"
• summary starting with "sat:"

[soxofaan]

yes, I could easily add "eo:bands" there, but I wanted to add some parsing/validation too, in the style of the other "models".
However, I'm bit confused on how to do that, see e.g. #82

has this been fixed by these commits, or still an issue?

[soxofaan]

It's been a while, I'm not sure. Have to find some time to verify this
