[BUG] Light Sensor TCA Scan

[ineskhou]

Summary

V5d Flight Controller Board with solar panel boards today. When trying to access V2 Solar Panel sensors via the TCA the CircuitPython code would throw timeout errors unless you scan the core I2C bus it is on before trying to access any of the TCA I2C buses. The act of doing the address scan makes the TCA work and stop timing out.

good news is that our new I2C buffer seems to be protecting the core I2C buses from any issues propagating up from the multiplexed I2C buses

Steps to reproduce
