Update observing methods

[wtgee]

• Changes observatory.observe to observatory.take_observation to have more descriptive name and not interfere with potential state action names.
• take_observation will now remove cameras if they are stuck and try to continue observing until no cameras are left.
• Created high-level pocs.observe_target, which loops over the exptimes in the observation and sets up processing threads when done with each exposure. This replaces what was in the observing state and moves it to a pocs method. This allows the mount to stay on a target for the length of the observation without moving between states during each exposures, which helps cadence.
• Relies on python 3.10 from #1174

Comes from #1167
