readRawAccel() conversion error

[TzOk83]

There is a bug which reveals itself on 16 or 32 bit MPUs. RAW acceleration is returned via 2 8-bit registers, but is signed, and 2's complement encoded. Registers are mapped as uint8_t (unsigned 8-bit), which is fine, but they are bitshifted and ORed together and assigned to float variable.
xha << 8 | xla creates xa, but it's type is uint16_t, while it should be int16_t... both can be assigned to float variable, but only second one is valid.

Is:

ra.XAxis = xha << 8 | xla;
ra.YAxis = yha << 8 | yla;
ra.ZAxis = zha << 8 | zla;

Should be:

ra.XAxis = (int16_t)(xha << 8 | xla);
ra.YAxis = (int16_t)(yha << 8 | yla);
ra.ZAxis = (int16_t)(zha << 8 | zla);

thx man, this saves me a lot of time and searching!
(was running it on esp32)
