Test/add Windows support

[hugows]

Hi,
since this is written in a modern language, I had the expectation it would work on Windows as well.

I'll fire up windows today and get it working!

I think its a termion thing, unfortunately..

termion claims it will work on any system with an ansi terminal, so later today I'll try it out on bash for windows

[hugows]

That will probably work, I didn't try that.

I tried installing this to my windows using cargo install with git bash but with no luck.

Here's the error message:

@mrZalli thank you for testing this out! it seems like I should investigate alternative terminal libraries. I use pretty basic functionality, so another one may be able to be swapped in without too much effort.

To whom it may interest: I had a rough try at porting void to crossterm (for native, non-WSL Windows support) here: https://github.com/pmf/void/tree/crossterm-for-windows-support

Issues that I'll still have to handle:

• some ugliness in function signatures introduced due to my unfamiliarity with Rust
• I had to dumb down the "atomic saving" feature because Windows complained about locking
• the "open in external editor" feature does not work

Would be good if someone who is more familiar with void could try it out and compare performance under Linux (I've just compared the Linux termios and crossterm versions in a VM, and not with large files) and check what other features might be broken that I do not know of.
