Turn off typechecking

[lastmjs]

It would be nice to have the option of turning off type checking. I rely on the editor for type checking, and we don't enforce type checking with this part of the build process, so it just needlessly slows down compilation

You can pass a custom tsconfig on my fork: https://github.com/KingDarBoja/serverless-plugin-typescript#readme

See the tsconfig ref at the official webpage.

I have no idea how to disable type checking at the moment, I will investigate
