Fix CDC fallback logic/path, add ESP32 CDC examples by Syndric · Pull Request #22 · bertmelis/USBHostSerial · GitHub

Fix CDC fallback paths to work with dual ESP32, one as a host and the other as a peripheral.

Fixed a small typo, host_line_coding was being get, not set
Asserted the USB control line. Otherwise, communication only works one way from Host -> Peripheral.
Added examples for ease of testing
Fixed panic if invalid state upon CDC disconnect
Fix reconnection logic with semaphore
Added delays to allow for CDC to stabilize (use case: pressing the reset on peripheral)
