Fix pin names for MAX30102 symbol

The red-led and ir-led pin names were swapped. Should be: 5=IR_DRV, 6=R_DRV.

This is direct outputs of the LEDs. INFRA-RED LED cathode pin5 and RED LED cathode pin6. Easy to check on the device because the red led is visible.

By the way, the datasheet mentioned in the library https://datasheets.maximintegrated.com/en/ds/MAX30102.pdf notes that these pins shouldn't be connected to anything (N.C., floating). Thus, this is not destructive change.
