feat: way nicer error when typing an import statement wrong [APE-1152]

[antazoey]

What I did

Better error when you type an import wrong and stuff, like this:

import "@openzeppelin/contracts/proxy/beacon/IdBeacon.sol";

see, i spelled it wrong, and it failed with FileNotFoundError which wasn't bad but was kinda unexpected.
If I let it slide to the compiler, the message was really nasty tho.

So here i made it ideal

How I did it

check for missing files and raise a nice pretty message if you find any.

How to verify it

see my sol example at top
