No NEOPIXEL alias for GPIO18 on espressif_saola_1_wroom ( vs. wrover )

[d-c-d]

I am very happy to have NEOPIXEL working ( thank you all), but noticed this unexpected difference between the WROOM and the WROVER boards

No NEOPIXEL in dir(board)

Adafruit CircuitPython 6.0.0-alpha.2-216-gbbac68e77 on 2020-08-11; Saola 1 w/Wroom with ESP32S2

import board
dir(board)

$ git blame espressif_saola_1_wroom/pins.c | grep GPIO18

but the WROVER does have a NEOPIXEL alias for GPIO18

$ git blame espressif_saola_1_wrover/pins.c | g GPIO18
6aaab00 (Scott Shawcroft 2020-04-17 16:23:28 -0700 24) { MP_ROM_QSTR(MP_QSTR_IO18), MP_ROM_PTR(&pin_GPIO18) },

@d-c-d Want to add it? It should be straightforward.

Slipped my mind when I added the mpconfig for the wroom, my bad.
