Migrate to TypeScript

[promaty]

After building ipfs-pinner, I realized we can save a lot of time on developing and debugging just by using Typescript.
We don't need to convert everything at once, we can start doing one file at a time and transpile it using Babel.

I would start with the shared libraries, they currently don't use babel at all and we are using CommonJs while everything else is ECMA for some reason
