Providing /contributions response as a downloadable file

[FabiKo117]

The response of the newly implemented /contributions/(latest)/geometry|bbox|centroid endpoints can also get quite big. Therefore, it would make sense to provide it in the compressed gzip format, as it is already done with responses for the /elements and /elementsFullHistory endpoints.

The following lines in the RequestFilter.java class would have to be extended to also support the /contributions:

ohsome-api/src/main/java/org/heigit/ohsome/ohsomeapi/filter/RequestFilter.java

Line 48 in d890d5d

if (RequestUtils.isDataExtraction(request.getRequestURL().toString())) {
