Add path aliases for cleaner imports

[matux]

Description of the change

I was getting tired of the relative subdirs when doing imports and checked if there's an idiomatic way of improving how we can refer to different paths without crawling for directories. Turns out there's, path aliases.

Added some configuration and updated the imports and it seems to be working just fine. Although I don't know if this could generate other issues for SDK users.

[!NOTE] I didn't change all the files, just the ones I've been working with recently, just as a PoC. If you guys want, I can propagate this to the rest of the SDK.
