ESP-01 header renamed to AUX, and expanded to 12 pins from 8 pins. Pins 1-8 still accommodate the ESP-01, with expansion to full SERCOM 4-pad support to allow for SPI and I2C on that expansion port with additional GPIO control. Update pins.c with additional signals provided AUX_1-8, along with UART, SPI, I2C name usage as aliases to appropriate AUX_1-8 signals. Additionally, add several alternate names specific to several expansion modules - the ESP-01, and the ATW-01 using the WINC_1500 (SPI) w/interrupt and control needed for the WINC - with assignments to module pin positions. Re-work SERCOM assignments to accommodate the above from other parts of the board, which required moving a SERCOM or two around in order to accommodate the 4-pad sercom pin mapping on the AUX port. Built and tested using latest from 'main': Adafruit CircuitPython 6.2.0-rc.0-70-ga1562430f-dirty on 2021-04-05; BDMICRO VINA-D51 with samd51n20
