adding code for the alphanumeric countdown clock

[BlitzCityDIY]

Adding code for the alphanumeric countdown clock. Uses three alphanumeric displays with a qt py esp32-s2. gets the time from adafruit IO and compares it to the time set for the event at the top of the code.

looks like it's failing here on CI:

I think the actual error is "error: 'SPI' was not declared in this scope":

The other says "warning:" so it should not stop or fail the build process.

The CI was set to test for Gemma when it's a Trinket guide. So that's been changed but waiting for CI

@caternuson do you have a moment to take a look at this? It looks like the library always expects 'SPI' to be available, but https://github.com/adafruit/Adafruit_BusIO/blob/master/Adafruit_SPIDevice.h doesn't define SPI if SPI_INTERFACES_COUNT is zero or undefined. However, this is not a recent change, so not sure why it didn't come up before now.

[caternuson]

It's because of this:
adafruit/Adafruit_LiquidCrystal#15
with the real issue being with the current state of the MCP23017 library - that's the one that expects/requires SPI and Wire to exist.

For now, to get this PR to pass CI, suggest adding a gemma.test.skip file to the PR.

[BlitzCityDIY]

great, thanks @caternuson ! i'll add that

[TheKitty]

Skip files can be picky. I suggest cancelling this PR and put in a new one with the exact current files.

[BlitzCityDIY]

going to be trying with a new PR to include the skip on initial commit
