Summary file fixes

[DOH-HNH0303]

-Fixed spelling error in Seqera file output report name: Summarry --> Summary
-Fixed microreact output to /report instead of /reports so now microreact files populate the Seqera outputs tab correctly
-Added run-summary.csv to tower.yml

[DOH-HNH0303]

Addressed MEP request to add back in the MEAN_SNP_DIST, MIN_SNP_DIST, or MAX_SNP_DIST columns in the microreact files (and summary.csv files as a result). These values are calculated ignoring the reference SNP distances since the reference is a copy of a production seq - including the reference genome in the SNP dist calculations would bias the mean SNP dist overall towards the reference genome and would give a false minimum SNP dist for the seq that was used as reference.

[DOH-JDJ0303]

@DOH-HNH0303 - looks really good! How do you feel about integrating the SNP stats process into bigbacter_report_cluster.py or just adding it as a standard output for polycore?
