12-Thermopile-Shield Openmv examples does not works

[Kabron287]

Board with STM32F750
I used PB10 as SCL and PB11 as SDA signals for MLX90640
I see clock and data signals on scope at 100kHz when fir.init() executed, but then I got error message:
ValueError: Failed to detect a supported FIR sensor.
These examples works fine with the original Openmv H7 board.

FW used: 4.3.1, Openmv: IDE 2.9.2

1. It is definite bug in current FW. Look at the screenshot, MLX90640 address (0x33) is found correctly, but then nothing happened.
2. There is no definition for FIR_MLX90640 at all in FW.
   Extended command fir.init(type = fir.FIR_MLX90640) allow to skip address searching, but in current FW version I got:
   AttributeError: 'module' object has no attribute 'FIR_MLX90640'
   error

I am interested to find a solution for this as well. Thanks Kabron287 for your trouble shooting.
