Fastcov hides the details of some of its internal processing to prevent the shell from being spammed with noisy traces. However, this may be desirable for debugging and understanding what fastcov is filtering and why.

Add --verbose option that prints extra information containing potentially useful internal processing details.

@astratsx FYI - I've created a new branch to add a --verbose flag to fastcov. Here is sample output when run against the fastcov example project:

I still need to add a few more debug traces and tests, but I will most likely open a PR and merge within a few days. After that I'm going to tag and release v1.5 of fastcov since there have been quite a few new features added since v1.4
