code error in getGravity, X values used for Y and Z

[bradcar]

Fouind a coding error in lines 510-516. This is likely a copy-paste error, as the X quatity is given to X, as well as Y and Z.

void BNO08x::getGravity(float &x, float &y, float &z, uint8_t &accuracy)
{
	x = qToFloat(gravityX, gravity_Q1);
	y = qToFloat(gravityX, gravity_Q1);
	z = qToFloat(gravityX, gravity_Q1);
	accuracy = gravityAccuracy;
}

Likely this should be:

void BNO08x::getGravity(float &x, float &y, float &z, uint8_t &accuracy)
{
	x = qToFloat(gravityX, gravity_Q1);
	y = qToFloat(gravityY, gravity_Q1);
	z = qToFloat(gravityZ, gravity_Q1);
	accuracy = gravityAccuracy;
}

Sorry, I do not have any way of testing this code, so I can not do a PR.
