This change adds support for the ESP32-C3, a new chip from Espressif. It is a RISC-V core so porting was comparatively easy. Most peripherals are shared with the (original) ESP32 chip, but with subtle differences. Also, the SVD file I've used gives some peripherals/registers a different name which makes sharing code harder. Eventually, when an official SVD file for the ESP32 is released, I expect that a lot of code can be shared between the two chips.
