Suggest stronger approach for saving/restoring files per pane

[Matthew-Whitlock]

This is targeting the history file, but works for files or directories.

Undying fame and adulation for whoever makes this file saving approach into a baseline feature of tmux-resurrect with just a config like set -g @resurrect-capture-files '$HOME/.bash_history.d/bash_history_{{PANE_ID}};$HOME/.my-other-{{PANE_ID}}-file.txt'
