Booting Data Collection

[flynn248]

Booting up the data collection has gotten easier, but can be improved further.

1. The initialize_collection.sh file can be updated to account for it having been run once before. Or, separate the chrony time sync from the file to save 30ish seconds when booting up the sensors.
2. Ensure that the log directory located in the home directory exists before continuing the process.
3. The most important thing is adding some kind of check to ensure that a sensor loaded correctly. This is easy to visually see with the lidar and routers since the lidar spins and the routers have an led that flickers rapidly. However, this method is not ideal for the USB cameras which have nothing that can be visually seen without looking at the logs. This step is important, but may be best to wait until the web application is addressed more to see what format that requires. Any ideas can be submitted on this issue.
