Add ability to pass path to codeshift.config.js

[EliteUser]

Hello again! Thanks for great tool btw 😃 I'm building a tool which is actually a wrapper around yours. It is a standalone package which contain all codemods and it just runs @codeshift/cli internally.

My package, after installation is located in node_modules and have following structure:

The problem is that after I install my package and run it, @codeshift/cli is not able to find codeshift.config.js, because it is trying to find it in project root, but config is actually located in node_modules/@my-tool/codeshift.config.js.

I think I can solve this problem if I can pass --config option (or something like this) and specify a path to config (like node_modules/@my-tool/codeshift.config.js).

Maybe there is another solution, can you help me?
