Firefly detector list should include more than just detectors

[canismarko]

There are some situations where you want an Ophyd device to be included as a detector even though it's not what we typically think of as a detector. An example from the recent beamtime with Jerry Seidler's group.

Each crystal analyzer has the following structure, where there individual items are positioners.

Analyzer
|- energy
|- horizontal
|- vertical
|- crystal_yaw
|- reflection
|- ...

Users wanted to do a scan on analyzer.energy, e.g. bp.scan([I0, IpreKB], analyzer.energy, 7800, 7820). However, at each point in the scan, they also wanted to know the values for the other positioners, especially energy.horizontal. In Bluesky, this is easy, just include the analyzer as a detector: bp.scan([I0, IpreKB, analyzer], analyzer.energy, 7800, 7820). However Firefly only shows things with the "detectors" label right now.

Proposed Behavior

99% of the time, the list of options should just be things with the "detectors" label. However, we need a way to also include all the devices.

Maybe we can re-use the component selector for this?

Maybe the detector list is something where you can choose from a list and have to move the selection over to a second list. That way the source list could change depending on whether you want just detectors, or everything. Just an idea, not necessarily the best option. Here's a mockup of what I was thinking.

Another thought I had, instead of putting tabs into the detector selector, maybe we should put a combobox at the top of the component selector with all the different labels, like "detectors", "ion_chambers", "motors", "all devices", etc.
