[ENHANCEMENT]: Support for package.json import aliases

[AndreaPontrandolfo]

It would be nice if this library supported package.json import specifiers too, instead of just Typescript aliases.

It should be pretty easy with package-up

Probably this use case may be resolved with issue #34

User may manually import package.json file and provide aliases from there to a new option.
This solution also cover any other imlementations of aliases

I would love to see this too

I tried to do this myself here, it's just an experiment, a naive implementation completely unusable in the real world. Maybe i will get back to it if i find the time.
