opencover and cobertura reports generated at the same time overwrite eachother

[Smith00101010]

Hi,

thank you very much for this tool, it is very useful.

I was thrilled when #75 was implemented to allow me to create opencover and cobertura reports at the same time, as different tools need different inputs.

Maybe I am overlooking something, but when I try to use it, the reports overwrite each other as they have the same file extension (.xml).

I used /p:CoverletOutputFormat=\"opencover,cobertura\" and coverlet reported as expected:

Generating report 'C:....\coverage.xml'
Generating report 'C:....\coverage.xml'

Is there a way to avoid this? Maybe coverlet could add the format to the file name (Either by default or if a flag is set). So in my case it would create "coverage.opencover.xml" and "coverage.cobertura.xml".

I could help implementing it, if you do not have the time.
