Suggestion=> adjust :Copilot setup to accept an argument of "bindings"

I think it would he cool to have a couple of features added a new optional parameter under setup that created a file and appended it somewhere in your runtime path that contained only the various mappings of keys and allowed you to modify them

Another cool feature would be configure mappings where it launches an interpreter and captures input from stdin for ctrl + keys then stores them to a text file and reads from that to determine keybindings on a key by key basis. I had to write a really aggressive dismiss:
```
inoremap (copilot-dismiss):startinsertcall copilot#Dismiss()
```

Because for whatever reason whenever i would dismiss a suggestion it would immediately pop back up on the starts of new lines.
