Needed this so the E2E test could use it after converting internal/e2e into a submodule.

This is only handling pointer-protobufs to non-pointer-stdlib conversions for now, which is the most common.

This is the target side of the conversion.

Variation of astAssign that works for generating foo, bar := gir, zim instead of just foo := gir

We specifically ignore the error here by assigning to the blank identifier.

I really should've had this return an error instead of a boolean the first time, so i fixed that since i found it useful to return a real error in the case where you are using protobufs but not in the exact way this PR handles.

We always generate both the TO and FROM functions at the same time, so when we apply the protobuf conversion in reverse we have to flip the direction so the function we use switches as well.

TODO: I was going to figure out how to use this attribute to determine protobuf versions so the generated code could freely switch to different conversion functions if needed.

These are the key functions here. They infer if we should be trying the special casing of protobuf time/duration conversions.
