Imaging Node cleanup and added in two new services: zoom and position

[Dat-Bois]

Summary

• Added in two new services to enable changing the zoom and position of the camera in the imaging node.
• Also fixed an issue with the localizer only running once.
• Also made it so that the camera point down message is not sent everytime we wanna take a picture. (Currently an arbitrary 5 degree error is acceptable)

Test Plan

None, I'm goated.
