Usage of Wire library.

[Koepel]

In the file "APDS9930/src/APDS9930.cpp", the function "wireWriteDataBlock()" is not used, but it contains a bug.

The sequence should be: beginTransmission - write - write - write - endTransmission
However, instead of writing data, both Wire.beginTransmission() and Wire.write() are called (multiple) times.
The extra Wire.beginTransmission() is at the moment in line 1082. That line may be removed.

A similar issue is in the original code from Sparkfun.
