Description of Change
This PR adds support for Espoir, a mikroBUS PoE+ devboard, by Connaxio inc. However, the ESP32-MINI-1 is a single core CPU, so Connaxio will provide the builds for its devboard until single core CPUs are officially supported. Adding these modifications to the official repository will limit discrepancies between Connaxio's fork and the main repo.
Tests scenarios
Tests include Ethernet, SPI, USB, I2C, UART (1-wire).
