Add updated ref genomes [SARSCOV2]

[katerinaoleynikova]

Good day,

I would like to know how to implement a new version of the ref genome more correctly: I mean where it can be retrieved from, which way to put it into the dirs, etc.?

My results show all the time that the highest percents belong to the Wuhan type, but I definitely know that it is the new one.

Thank you,
Best wishes
