Add cheatsheet

[danielballan]

This adds a cheat sheet, based on the content in 10 minutes to Tiled.

It might need to be made more compact; it would be nice if it printed onto single sheet of paper in PDF form, like the conda cheat sheet.

Closes #672

Looks great so far. Looks useful for a client that directly does analysis. I imagine printing out a page like this at a beamline and taping it to a wall for users to reference.

I feel like the installation part might not be necessary. You probably won't be installing tiled often so we might want to use that space for a more common operation.

Good feedback. I didn't plan to include it at first, but noticed that conda did. Perhaps a more concise statement like, "With pip or uv, install "tiled[client]". WIth conda or pixi, install tiled-client (available via conda-forge).
