This feature makes use of the NCBI API https://www.ncbi.nlm.nih.gov/datasets/docs/v2/api/rest-api/ - Add support for building GTDB databases
- Speed up decompression in
k2by usingzlibinstead ofgzipmakingk2competitive with native gzip binaries - Change the way accessions are downloaded when using NCBI API so that downloads are more reliable
