* Updated library to reflect latest ESP32SPI references `set_crt`, not `set_crt`.
* Removed `certificates.py` file, loading certificates from the `CIRCUITPY` filesystem instead.
* Updated examples

To use in CircuitPython, simply install the [Adafruit CircuitPython bundle](https://github.com/adafruit/Adafruit_CircuitPython_Bundle).
