Make it possible to specify the tsconfig.json

[endel]

Would be great to allow to specify a different tsconfig.json file to use.

A practical example is that our tsconfig.json doesn't include the test files. We have a different tsconfig.test.json, which do include them.

Given this scenario, it might make sense to either allow to specify a different tsconfig.json file to use, or allow a "files" key in the tsfmt.json.

What's your thoughts about this?
Cheers!

I have something similar. I'd like for us to be able to specify which file I use for the configuration of tsfmt.
please consider adding a "-c" or "--config" parameter.
