Remove alias function

[fkautz]

Now that we generate package imports automagically, the alias function is likely not necessary anymore. Would possibly be good to remove it.

Right now we calculate the package alias types by hard coding a list of "known" types within each each package

I believe we can build these types in at compile time somehow (I am assuming similarly to how we use _embed.sh.

The other option would be to look up the package types at runtime.

Either way - we should be able to make the alias concern "full proof" so that we are not responsible for maintaining a hard-coded list of these.
