Feature request: add -r recursive option

[maikeriva]

Hi! I am really enjoying this tool, but I recently found that it lacks a -r recursive option.

Currently, it seems I can either:

• Parse all the project files
• Parse a specific file (or files, using wildcards *)

But if I want to parse only a specific folder and all its sub-folders and files in it, that doesn't seem possible. In many CLI tools this is often achievable with a -r option (for example: cp -r /some/sub/folder) thus I think it would be nice to have this for ts-auto-guard too.

That seems reasonable. Shouldn't be too hard to add. You want to open a PR?

Did you try doing ts-auto-guard /some/sub/folder/**/*.ts btw? Blob support makes more sense than -r imo.
