v0.0.9

• BREAKING: Merge KeybindDispatcher into Keybinds. Now Keybinds directly has dispatch method and dispatches actions. This change makes the API simpler. Note that setting different timeout values to compared objects makes == operator return false even if the key bindings are completely equal.
• BREAKING: Rewrite KeySeq using smallvec. Now it is a struct instead of enum and it no longer allows accessing the internal state.
  • Key sequences containing up to 2 key inputs can be allocated on stack instead of heap (previously only a single key input could be allocated on stack).
  • KeySeq now implements Hash trait.
  • Methods for adding inputs to a key sequence were implemented.
• BREAKING: Replace Key::F(u8) variant with Key::F1...Key::F35 variants. This change brings the following benefits.
  • The size of Key was reduced from 8 bytes to 4 bytes because u8 value required a 3 bytes padding.
  • Invalid keys such as Key::F(0) or Key::F(99) are now not possible.
• Implement Extend for Keybinds to append multiple key bindings.
• Fix crossterm's button release event is not ignored as Key::Ignored.
• Fix an empty key sequence does not cause an error on serialization.
• Explain the crate features in Cargo.toml.
