Fixed Seg Fault in getImuToCameraExtrinsics

[saching13]

Addresses #155

I presume segfault happened becasue of line 347, accessing tranformationMatrix which is empty?

If thats the case, please place a check there as well, could be empty in different cases.

Same applies to other places

std::vector<std::vector<float>> transformationMatrix = eepromData.imuExtrinsics.rotationMatrix;
The transformation matrix is a copy of the rotation matrix. So it will be empty only when rotation matrix is empty. And rotation matrix will be either empty or have 3x3 always.
Added to computeExtrinsicMatrix also. But I think it reach that point only if user writes to EEPROM their own custom one and misses to add the rotationMatrix.
