Don't rely on fs_extra

[cnpryer]

Instead of using fs_extra to copy mock directories to tempdirs for testing, we can just create our own dir copying function.

Add to huak::utils::path a function copy_dir to copy one directory into another target dir.

Are you looking for a custom copy_dir or just a lock-in copy of https://github.com/webdesus/fs_extra/blob/master/src/dir.rs ?

Also do you want to keep the error codes of fs_extra or use IOError from https://github.com/cnpryer/huak/blob/master/src/huak/errors.rs for every error?

Note: I sent you a friend request on Discord.

IIRC we're only using copy_dir to copy a mock project (from resources dir) into a tempdir for tests. We don't need all the configuration or error handling. Just copy all contents from here to here. But...

I don't really want to do this for testing in the future. I'm hoping we can just hardcode tests as needed. As an example, if I want to test the fmt operations we can just hardcode an unformatted python function, serialize it to the tempdir, run, and then assert.

#[test]
fn test_fmt() {
    let py = r#"""\
def some_fn(
):
    pass
"""#;
    write(py, dir.join("mock.py"));
    let res = read(dir.join("mock.py"));
    let ans = r#"""\
def some_fn():
    pass
"""#;
    assert_eq!(res, ans);
}

I might be missing some edge cases. So we probably should wait to do this, but you get my point hopefully. At that point we should be able to rip copy_dir out altogether.
