hxc_rs

This is a minimal rust wrapper over the libxcfe library https://github.com/jfdelnero/HxCFloppyEmulator. I have only implemented the functionalities needed for my other project https://github.com/cpcsdk/rust.cpclib (mainly to allow basm assembler to write in HFE image discs). I have not made sound choices regarding mutability: all non mutable objects on the rust-side are still mutable on the c-side. I may have memory leaks, even if I tried to avoid them.

Feel free to provide patches to improve the cover of the wrapper, fix mistakes, or anything else. I can gladly provide the ownership of the repository to someone more motivated than me to continue this task (I will only add what I need for my main project).

x86_64-pc-windows-gnu is the required toolchain for windows: cargo +nightly-x86_64-pc-windows-gnu test. This may be a string limitation for the dependent crates.
