Update crossterm to 0.27.0 and bump minor version

[andrewtc]

Hello! I am currently developing a CLI app in my spare time using termimad. Long story short, I needed to update to the very latest version of crossterm so that I can suppress color output based on a command line argument. There were some breaking changes to the public interface in the latest version of crossterm (0.27.0), so I had to make edits to all of the following libraries locally in order to get everything to work:

termimad

Please see this MR

• Bumped crossterm version to 0.27.0 from =0.23.2
• Some places where KeyEvent was being initialized needed to be updated to initialize new members kind and state
• Added underline_color to CompoundStyle
• Increased crate version to 0.27.0 from 0.26.1

crokey

• Bumped crossterm version to 0.27.0 from 0.24.0
• Needed to make similar edits to a couple functions and the key! macro to initialize new KeyEvent members
• Increased crate version to 0.6.0 from 0.5.1

Please see this MR

• Bumped crossterm version to >=0.23.2 from =0.23.2 to resolve a compile error caused by mismatched crossterm versions
• Increased crate version to 0.8.1 from 0.8.0, since (AFAIK) this shouldn't be a breaking change

I ran tests and examples to ensure that everything was working as best I could. However, I would appreciate if you would give the changes a once-over and just verify that I haven't missed any broken behavior. Please note that I am developing on Windows and that I have very limited ability to test cross-platform. If you have a standard way of verifying these changes on Mac and Linux, please let me know if there is a way that I can help. Thank you!

Thanks. But I was working on a bigger PR also bringing crossterm to 0.27: #18

So closing this PR
