Title: Update Adafruit_PWMServoDriver.cpp  Fixed setPWM - beginTransmission now works

Hi!

So happy to be able to contribute.

Corrected setPWM. Transmission now works.

Line 53: Set MODE1 register to " old mode or 0xA1"
This enables autoincrement allowing multibyte transmissions to be sent.

Can now set a sequence of regsiters in one transmission.
