Show counts in autocomplete options

[fengelniederhammer]

Extend gs-lineage-filter , gs-location-filter and gs-text-input such that they show the count of the respective autocomplete options.

This requires #609, #653, #654

For the location filter this might actually be difficult:
We get counts for every value tuple that is in LAPIS (suppose (Europe, Germany, Bavaria) has 50 sequences, (Europe, Germany, null) has 20 sequences).

But we don't get counts for every value that we show in the filter (i.e. we don't know how many sequences we have for Europe, because there are no sequences that only have Europe but no other location value set. We also don't know how many sequences we have in Germany, because we only got how many sequences we have in Germany that also have "state = null").

This could maybe be solved by sending an aggregated request to LAPIS for every level in the hierarchy (in the example: also sending a request /aggregated&fields=region to get the counts for the continents and /aggregated?fields=region&fields=country to get the counts for the countries.)
