More licensing options for wider compatibility?

[Shnatsel]

First off, thank you for writing this crate!

There has recently been interest in adding PCX support to the image crate via your pcx crate for use in a game restoration project. However, there are some concerns about adding a dependency with a WTFPL license, as it may create legal ambiguity for some users of the image crate.

Would you be open to adding MIT and Apache-2.0 as possible licensing options, in addition to WTFPL? The typical licensing in the Rust ecosystem is MIT OR Apache-2.0, so WTFPL OR MIT OR Apache-2.0 would keep WTFPL as an option while also laying out clearly defined legal texts for those who might need that.

I think WTFPL is pretty unambiguous but I'm open to adding MIT and Apache-2.0 licenses as well. Though, I think we should also ask @mthiesen who has also contributed to this crate.

@mthiesen do you agree to change license of this crate to WTFPL OR MIT OR Apache-2.0 from just WTFPL?

My contributions to this project have been quite small. Feel free to choose any licence you like.

Thank you!

I see the license has been updated in git, so I'm going to go ahead and close this.

A release to crates.io would also be welcome, so that tools like cargo-deny wouldn't flag the crate.
