Configurable refresh

[Emoun]

I would be useful if we were able to configure whether the "refresh" outcome of expand could be turned off or result in a failure.

I specifically have a setup where I'd rather have a missing .expanded.rs file trigger a test failure and not create the expanded file for me. I like that the file could be created for me, but I'd prefer if it was only when I specifically ask for it.

A possible solution is simply adding another method that doesn't create expanded files when they are missing, simply failing instead:

#[test]
pub fn pass() {
    macrotest::expand_without_refresh("tests/expand/*.rs");
}

@Emoun

Sure, it seems straightforward to implement.

@eupn Thanks for the quick response and implementation. It seems to work as expected for me.
Much appreciated.

@Emoun sure, thank you for the feedback!
