Would love to have a --clean option when running a program directly

[mortax]

Currently, if i run a program directly, i.e.:

$ grain thing.gr

I am left with thing.gr.wasm and a target in the source directory:

$ ls
thing.gr
$ grain thing.gr 
$ ls
target/        thing.gr       thing.gr.wasm

I would love to be able to run a program without retained artifacts, e.g.:

$ ls
thing.gr
$ grain --clean thing.gr 
$ ls
thing.gr

This is off-topic and covered in #242

@mortax This is unfortunately extremely difficult with the current way the compiler is built and how caching works. We plan to support this once we have a proper build tool (codenamed Silo) where we'll be tracking each file compiled.
