make config flipped attribute consistent

[boeckhoff]

for motors flipped value is either true or false,
for encoders flipped value is either 1 or -1

this should be consistent, I suggest using true/false for both.

[JotaroS]

can you also point to the code or file to be fixed?

[boeckhoff]

in generated config.hpp under firmware/include/config/config.hpp properties look as follows:

const float encoderFlipped[] = { -1, -1, 1, -1, -1, 1 };

const bool motorFlipped[] = { true, true, false, true, true, false };

so files to modify would be
utils/scripts/generateHardwareConfig.js
and firmware files that access the flipped properties
