Apscale

- fixed a renaming issue for partial analysis that led to the bug, that all files were deleted after denoising.

- improved empty file handling
- no more remapping needed in the esv table generation. cluster sizes are directly read from the fasta files instead
- updated the readme to the latest version

- Added Vsearch 2.29 support

- Fixed a bug where multiprocessing broke the cutadapt execution

- Completly switched apscale to ESVs
- ESVs are no generated by individually denoising samples, leading to comparability of output sequences across different studies / pipeline runs
- Removed OTU clustering entirely
- Updated to the most recent search version (2.28)
- Added "unique_ID" to the final ESV table: This is a sha3_256 hash of the sequences and yields and unique ID for comparisons unlike "ESV_1" and so on
- A detailed explanation via protocols.io will follow soon!

- added compability with Vsearch 2.22 and higher for the denoising module
