fix EDF reader

[drammock]

• converts "missing channel type" warning to logger.info
• fixes bug where all channel loc fields in the info pointed to the same object in memory (so that when setting montage, all channels get the coords of whichever channel came last)
• updates sleep tutorial to reflect new channel name behavior
• fix the logic so that if user specifies stim_channel or misc args to read_raw_edf they don't get spurious warnings about unidentified channel types

@adam2392 can you look ?

This LGTM for the EDF reader part!

[drammock]

this is still missing a test that would have caught the previous error. probably something in mne/io/tests/test_meas_info.py... I'll try to get to that before I sign off today

[larsoner]

Maybe mne/io/tests/test_raw.py in _test_raw_reader? That gets run by all mne/io/* readers

[drammock]

locally the smoke test fails on main and passes on this branch, so assuming CIs all go green this is ready for merge.

[larsoner]

LGTM, whoever sees green first feel free to merge

[drammock]

hmm, all green except for a timeout on Windows 3.9 conda 🤷🏻

Thanks @drammock
