Customizing `butane embed`'s export location

[Nekidev]

The current butane embed command is great to be able to distribute files in a single binary, it'd be great if you could also customize the location of the exports. Something like butane embed [LOCATION] being location an optional argument could be great. Maybe making it remember the last location too (not to have to re-enter the location every time you run the command)?

This is great to make butane fit better into the user's project structure. E.g. I have

project/
  .butane/
  src/
    main.rs
    db/
      mod.rs
      models.rs

and being able to fit butane_migrations.rs into project/src/db/migrations.rs would be amazing.

I'm open to making a PR for this

@Nekidev , this is a good idea.

https://github.com/Electron100/butane/blob/6848ef3/butane_cli/src/lib.rs#L35-L37 would be where the location can be remembered.

Great, I'll open a PR for this as soon as I get some free time.
