Bug: returning magnetometer values in wrong order | Fixed incorrect return order in _raw_magnetic.

[Arduino3128]

Hi,
Just noticed the values that are being returned from _raw_magnetic function are in wrong order:

Adafruit_CircuitPython_LSM303DLH_Mag/adafruit_lsm303dlh_mag.py

Line 142 in 6d2fec3

return (raw_values[0], raw_values[2], raw_values[1])

According to the datasheet of LSM303DLH, the register 0x03-0x04 is for X channel, 0x05-0x06 for Y channel and 0x07-0x08 for Z channel.

The address of the registers Y and Z are also interchanged in the declaration, which could have given the correct output, but it looks like the library is fetching readings from all 6 registers simultaneously and not though the defined addresses in line 51 to 54:

Adafruit_CircuitPython_LSM303DLH_Mag/adafruit_lsm303dlh_mag.py

Line 140 in 6d2fec3

self._read_bytes(self._mag_device, _REG_MAG_OUT_X_H_M, 6, self._BUFFER)

Adafruit_CircuitPython_LSM303DLH_Mag/adafruit_lsm303dlh_mag.py

Lines 49 to 54 in 6d2fec3

	_REG_MAG_OUT_X_H_M = const(0x03)
	_REG_MAG_OUT_X_L_M = const(0x04)
	_REG_MAG_OUT_Z_H_M = const(0x05)
	_REG_MAG_OUT_Z_L_M = const(0x06)
	_REG_MAG_OUT_Y_H_M = const(0x07)
	_REG_MAG_OUT_Y_L_M = const(0x08)

Hence while returning it is returning in order X,Z,Y.

This repository is actually for the LSM303DLHC, where the registers are actually correct as is:

I'm going to close this since it's not actually a driver problem but a documentation problem. I'll create an issue for specifying that this is NOT the LSM303DLH proper, for which your changes are correct. If you want to tackle that change to help make that distinction more apparent, go for it!
