Check snpit results against tbprofiler and correct when necessary

[dfornika]

Fixes #18

This is the approach taken:

• Check the outputs from snpit. If the Species is not N/A, then make no changes.
• If the Species is N/A then check the lineages in the tbprofiler full_report.json file. If the main_lin is lineage4 and the pct_reads_mapped is above 98% then:
• Change Species to M. tuberculosis
• Change Lineage to match the main_lin value from tbprofiler (should be Lineage 4)
• Change Percentage to N/A (since the outputs are not directly based on SNP genotypes)

Looks great!
