Vyper interface files (`.vyi`) do not appear as interfaces in `project`

[fubuloubu]

Overview

The vyper plugin does not currently generate Vyper ABI artifacts for .vyi interface files:

contracts/
  StreamFactory.vy
  StreamManager.vy
  Validator.vyi

$ ape console
In [1]: print(project.Validator.contract_type)
ERROR: (ApeAttributeError) 'LocalProject' object has no attribute 'Validator'. Also checked extra(s) 'contracts'.

Specification

The plugin should be able to do this natively. For now, the workaround is that you can place a <Interface>.json in your contracts folder (with hopefully the same ABI) and the pm "compiler" will grab it. Obviously a potentially source for human error, but it works

APE-1833 Vyper interface files (`.vyi`) do not appear as interfaces in `project`

I get error in vyper when I try to compile interfaces, like:

ERROR: (VyperCompileError) contracts/interfaces/IFaceZeroFour.vyi
StructureException:`...` is not allowed in `.vy` files! Did you mean to import me as a `.vyi` file?

^ very odd error, may be a bug in vyper even

Maybe they need special output selection.

I get this same error when running vyper directly:

vyper contracts/interfaces/IFaceZeroFour.vyi

you can't actually "compile" them, but I think -f abi should work

I tried this but got the same error.
