OverflowError: Python integer 256 out of bounds for uint8

[EUA]

It was working before but... When I try now, it complains from uint8 overflow.
only with tc001v4.2.py. RAW one works proper.

Traceback (most recent call last):
  File "/home/compile/PyThermalCamera/src/./tc001v4.2.py", line 108, in <module>
    lo = lo*256
         ~~^~~~
OverflowError: Python integer 256 out of bounds for uint8

Not sure if this is because of the code design specifically laid out for a RPi.
I fixed this on SteamOS by doing a conversion and it appears that all resulting values are correct.
Ideally the code should be tested against multiple distros with dedicated methods such as is_raspberrypi() is doing.

lo = lo.astype(np.uint16) * 256

There may be better ways to do this. And converting all parameters that are affected by the out of bonds multplication is required for:
lo, lomax, lomin, loavg
