feature: ability to run zellij actions on specific panes or tabs

[uncomfyhalomacro]

One thing I noticed while using zellij is the lack of the feature to run "actions" on specific panes or tabs (tabs are essentially panes I believe).

My use case is when doing editor functionality to interact with zellij e.g. a neovim plugin or a kakoune script for kakoune. For example, I want to run cargo clippy on an existing pane, let's say the pane having the ID of 12. This can be accomplished with the write-chars command:

zellij action write-chars --pane-id 12 "cargo clippy"
zellij action write --pane-id 12 10

I quite missed this functionality from tmux to be able to do tasks on specific panes.
