Add HW SPI and HW I2C support for ESP32

Was this done? I am not getting anything shown using HW SPI with a SSD1331 (although the code seems works). The board is a TTGO T2 with an attached SSD1331 and works with SW SPI. That said, SW SPI is extremely slow taking more than 1 sec to fill the screen with text. The speed test shows a 3 fps in text and lower numbers for boxes. The same code works great with a 1306 through I2C.

Other libs are faster but I already have my code using this one and still they lack many cool features found here.

I can help in testing, but I am not sure I can be helpful digging into the hardware or low level coding.
