Adafruit-circuitpython-esp32spi

This release includes:
* Migrating this repository from Travis to GitHub Actions. This has no effect on the behavior of the code itself.

To use in CircuitPython, simply install the [Adafruit CircuitPython bundle](https://circuitpython.org/libraries).

To use in CPython, `pip3 install adafruit-circuitpython-esp32spi`.

Read the [docs](http://circuitpython.readthedocs.io/projects/esp32spi/en/latest/) for info on how to use it.

* https://github.com/adafruit/Adafruit_CircuitPython_ESP32SPI/pull/80 Added `set_analog_read` and `set_digital_read` command handlers for the digital/analog read functions in Adafruit's fork of nina-fw, v1.5.0. Thanks anecdata!

Adds `set_certificate` and `set_private_key` methods to ESP32SPI to reflect [the updated `WiFiSSLClient` in nina-fw](https://github.com/adafruit/nina-fw/pull/11).
* Use `set_certificate` and `set_private_key` to set your ESP32's certificate and private key. This will be used to authenticate your CircuitPython device to a server.
* To use these methods, [you _must_ update the nina-fw version on your ESP32 Co-Processor/AirLift to version 1.4.0 or above.](https://learn.adafruit.com/upgrading-esp32-firmware)
