Think about how reader is chosen

[TimMonko]

🧰 Task

Currently there are two paths, and they have crossover and need to figure out the best way. I need to reduce the duplicated logic here. And probably find a way to also use determine_plugin() from bioio a bit more cleanly for shared logic, because this would be more consistent than grabbing the first in the list (bioio grabs the most recently installed)
