[Feature request] SSH compatibility

Hi,

Thanks for using the plugin! I'm glad to hear that you're enjoying the integration.

That's a good idea. Unfortunately, I'm currently pretty busy and won't be able to take a look at this for another three weeks. However, if you want to give it a try yourself, here are some pointers on how to solve the problem:

Install Kitty on the Remote Machine: Ensure that Kitty is installed on the remote machine. You can use the following commands to install Kitty using Linux brew:

wget https://github.com/kovidgoyal/kitty/releases/download/v0.20.3/kitty-0.20.3-x86_64.txz -O kitty.txz
mkdir $HOMEBREW_PREFIX/Cellar/kitty
tar xf kitty.txz -C $HOMEBREW_PREFIX/Cellar/kitty
ln -sf $HOMEBREW_PREFIX/Cellar/kitty/bin/kitty $HOMEBREW_PREFIX/bin
rm kitty.txz

Enable Remote Control in Kitty: Configure Kitty to allow remote control by adding the following lines to the ~/.config/kitty/kitty.conf file on both local and remote machines:
```
allow_remote_control yes
listen_on unix:/tmp/mykitty
```
Alternatively, you can start Kitty with the following command:
```
kitty -o allow_remote_control=yes --listen-on unix:/tmp/mykitty
```
Set Up SSH Port Forwarding: To forward the Kitty remote control socket over SSH, use the following command when connecting to the remote machine:
```
ssh -R 50000:${KITTY_LISTEN_ON#*:} user@host
```
You can also add an alias to your shell configuration file (e.g., .zshrc or .bashrc) to simplify this step:
```
alias ssh='ssh -R 50000:${KITTY_LISTEN_ON#*:}'
```

Configure Environment Variables: On the remote machine, add the following snippet to your shell configuration file (e.g., .zshrc):

if [[ $SSH_TTY ]] && ! [ -n "$TMUX" ]; then
 export KITTY_PORT=$(kitty @ ls 2>/dev/null | grep "[0-9]:/tmp/mykitty" | head -n 1 | cut -d : -f 1 | cut -d \" -f 2)
fi

Update Kitty Navigator Configuration: Ensure that the key bindings for navigating between Kitty windows and Neovim splits are correctly set in the ~/.config/kitty/kitty.conf file:

map ctrl+j kitten pass_keys.py neighboring_window bottom ctrl+j
map ctrl+k kitten pass_keys.py neighboring_window top ctrl+k
map ctrl+h kitten pass_keys.py neighboring_window left ctrl+h
map ctrl+l kitten pass_keys.py neighboring_window right ctrl+l

Install and Configure the Plugin: Ensure that the munsman/kitty-navigator.nvim plugin is installed and configured in Neovim. You can use a package manager like Lazy.nvim:

require("lazy").setup({
 "MunsMan/kitty-navigator.nvim",
 build = {
   "cp navigate_kitty.py ~/.config/kitty",
   "cp pass_keys.py ~/.config/kitty",
 },
 opts = {
   keybindings = {
     left = "<C-h>",
     down = "<C-j>",
     up = "<C-k>",
     right = "<C-l>",
   },
 },
})

Test the Configuration: Restart Kitty and Neovim, and test the navigation to ensure that the key bindings work seamlessly both locally and over SSH.

You are welcome to give it a try and let me know if you run into any issues. I'll be able to take a closer look in a few weeks.
