Subject: [PATCH] fix: speed up compressing responses #717

Tests on a medium-sized data set (3552 sequences):
I measured request times of /sample/unalignedNucleotideSequences:
- uncompressed: 1300 ms, 65 MB
- gzip compressed: 3100 ms (before: 14 s), 8 MB
- zstd compressed: 970 ms (before: 7.4 s), 342 kB
