Improve ROV communication frequency

[calebthejett]

Currently, the computer talks to the ROV at about 6-8 Hz. Driving would be smoother and small movements would be easier with a higher refresh rate.

Communication frequency has been improved! However, I would love to see if we could improve it more (minimizing the sleep as much as possible [maybe to 0]). Making communication frequency as fast as possible!

Lets try overwriting the clock speed of i2c with Wire.setClock(400000). This should transfer data 4x faster as the default clock rate is 100 khz. Microcontroller documentation needs to be checked to make sure that this is supported.

Before that let's check comm speed with no i2c to make sure that that's the bottleneck
