fixes #22

Note: I added it's primary address 0x4B
as well as it's one alternate 0x4a by Solder jumper...

Again not sure as for QWiic_Button we (you) added the 0x6f which is default one, but it actually has 4 solder jumpers which gives it an address range of 0x60-0x6f

Used in the sparkfun apds-9960 lux rgb proximity sensor boards and clones.
