intermittent servo jitter on the upgraded pan-tilt platform

[salwans]

I purchased the updated Arducam pan tilt platform (B0283), and when I use the c-based demo code ("RunServoDemo"), I run into severe servo jitter. The issue is reproducible ~50% of the time. Sometimes the jitter starts immediately when I launch the demo program, and sometimes it starts a few seconds later.

I don't understand the code, but setting I2C_TIM to 60 (instead of 30) in "src/sccb_bus.h", seems to make the jitter go away. I was blindly trying out different changes when I made this observation. I do need to test for longer periods to confirm.

Is the above fix the proper way to address this issue?
