An embedded-hal implementation for Rust on ESP32 and ESP-IDF

• This crate is intended for usage in ESP32 embedded projects that utilize and link with the ESP-IDF SDK.
• For embedded projects that don't need Rust STD support, WiFi or BLE (and thus don't link with the ESP-IDF SDK), please check esp32-hal.

• The Rust ESP32 STD compiler fork
• The "Hello, World" demo
