CPU halt when use this lib

[RomeliFeng]

Hi.
I try to use this library communication with BH1730 on ESP32. And the cpu while halt on "begin" and "readLux" function.
I have fix this issues with remove "Wire.beginTransmission(BH1730_ADDR);" before "Wire.requestFrom(BH1730_ADDR, 1);" in "read8" and "read16". I think is a wrong use. "requestFrom" function will call slave address with read. "beginTransmission" is the start before write.
