file name spacing issue with gtt-get-accessions-from-gtdb

[AstrobioMike]

right now, if a search for a species-level taxon is done, it will retain the space in the output file name, e.g.:

gtt-get-accessions-from-GTDB -t "Bacillus_A anthracis"

creates files like: GTDB-Bacillus_A anthracis-species-accs.txt

Update the program such that if there are spaces in the input taxon query, it will replace them with dashes for the purposes of creating the output files. Maybe just do a string substitution replacing spaces on the final output file handle
