Feature Request: allow user-defined cheats to replace default cheats

[alexander-gabriel]

Imagine you prefer a different keybinding for some function over the default, and thus go on to change a plugin setting or remap a default key.
Imagine further you add an entry to your cheatsheet.txt to reflect this new reality.

Wouldn't it be great, if cheatsheet.nvim would now stop showing you two conflicting cheat entries for cheats that are defined elsewhere as well?

Maybe filtering based on the same description could work.
