bluesky-httpserver crashing on startup due to missing dependency 'pandas' in bluesky-queueserver

[JonasDevelops]

I am trying to start bluesky-httpserver in a virtual environment with no other packages installed. It crashes with the following error message:

Traceback (most recent call last):

ModuleNotFoundError: No module named 'pandas'

A likely cause could be the removal of dependencies in bluesky-queueserver v0.0.22.

After installing the package pandas in my virtual environment the startup works.

I realize that the solution might be to add pandas as a dependency to bluesky-queueserver, but I am getting the error when trying to use this package. For now I dont have problems when using the bluesky-queueserver package. Thats why I am posting the issue here.

Maybe it would be beneficial to have a simple test in the CI that checks if the application can be started without crashing directly since this issue seems to be similar to #56
