cblaster: a remote search tool for rapid identification and visualisation of homologous gene clusters

This release resolves some long standing bugs and adds support for searching against the ClusteredNR database.

What's Changed

• Initial support for searches against the ClusteredNR database (NR database clustered at 90% identity). To enable, specify nr_cluster_seq as a database when performing remote mode searches, e.g.: cblaster search -qf query.fasta -m remote -db nr_cluster_seq. This should give significantly faster remote searches compared to the regular NR database (which remains the default). Note that query sequences are only searched against NR cluster representative sequences; clusters are then expanded to include other sequences in the cluster, and hit data (identity, coverage, evalue, bitscore) for all member sequences are taken from the representative hit.
• Don't add empty sequences to DB so diamond does not fail by @biobeni in https://github.com/gamcil/cblaster/pull/122
• Fix GenBank parsing when first gene wraps chromosome start/end by @biobeni in https://github.com/gamcil/cblaster/pull/121
• Fix missing database and empty .fasta file error by @kaileyhh in https://github.com/gamcil/cblaster/pull/111
• Lowered default hitlist size to 500 to avoid BLAST result errors
• Fixed search bug caused by query sequence headers containing whitespace
