v2.1.4

Documentation for k2 has been added to the manual -- https://github.com/DerrickWood/kraken2/wiki/Manual#introducing-k2

Replace FASTA/Q parser with kseq resulting in significantly faster run-times when estimating database capacity
Add memory-mapping support to dump_table (kraken2-inspect)
Add support for many threads to dump_table (kraken2-inspect)
Add support for downloading accessions by project ID, taxon ID or accession number to k2. 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 k2 by using zlib instead of gzip making k2 competitive with native gzip binaries
Change the way accessions are downloaded when using NCBI API so that downloads are more reliable
Update SILVA from 138.1 to 138.2
