Tiled databroker how-to guide

Part of #190

Looks good! It would be great if you can make it testable like the other how-to-guides.

If you make it use .. testsetup::, .. testcode::, and optionally .. testoutput. Then we can test the code in the document using

pixi run doc-tests

I typically setup all of the assumptions and mock things in a hidden .. testsetup:: section at the top of the file, and then have the rest use that.

In some of them I even spin up a local tiled server:

blop/docs/source/how-to-guides/acquire-baseline.rst

Lines 68 to 73 in 8ee29a3

	server = SimpleTiledServer()
	logging.getLogger("httpx").setLevel(logging.WARNING)
	db = from_uri(server.uri)
	tiled_writer = TiledWriter(db)
	RE = RunEngine({})
	RE.subscribe(tiled_writer)

After that it should be good to merge!

Should remove the unnecessary databroker setup (you may need to remove the pinned version).

If you merge main in, I removed all of the deprecated code so it shouldn't be a problem anymore.
