Added a 'directory' setting for manipulating the lcov.info file at read time

[GavinPacini]

I had this issue when working on a windows machine but running my code inside a VM with Docker.

The lcov.info file contains paths which are based on the Docker container however I wanted them to be changed to Windows paths. I added options for this.

Example of common workarounds here: https://stackoverflow.com/questions/27734876/better-way-to-fix-mocha-lcov-output-using-sed

Thanks, Gavin

@alexandrudima Hi Alexandru, I am wondering if you had a chance to review this? It's a really great extension you have made and I think people would like this PR upstream.

Cheers, Gavin
