Remove the generation of *.info files

[brainstorm]

All the relevant information is found already on stdout already and JSON-like formatted output:

{
        "total_read_count": 1804624,
        "contaminated_reads": 4253,
        "total_hits": 2148086,
        "contamination_rate": 0.002357,
        "bloom_file":"facs/tests/data/bloom/Arabidopsis_thaliana_TAIR10.bloom"
}

Not only *.info files do not add valuable information to the one it's already present, but they get overwritten (only last run present) if multiple queries are performed against a particular sample.
