Add STEMMA QT Rotary Encoder i2c Component

[jrh4567]

This pull request adds the Adafruit I2C Stemma QT Rotary Encoder Breakout with NeoPixel to Wippersnapper_Components.

Product URL: adafruit.com/product/4991

I set the subcomponents to "unspecified" and "raw" for the encoder value and button, respectively - I didn't see anything better in the list of i2c sensor types.

Hi @jrh4567 👋 Thanks for your contribution, it all looks fine for now!
We haven't actually got a great option for output type that would suit this device. I had thought we were going to add a boolean option to Adafruit_Sensor, but maybe that wasn't needed yet. I'm also unsure what effect using unspecified will have. If it was me I would use raw and raw, then also specify a display name for each subcomponent, in effect having two blocks similar to https://github.com/adafruit/Wippersnapper_Components/blob/main/components/i2c/stemma_soil/definition.json#L11-L14

Also good work on making it past the CI checks. I see you've also cloned the main WipperSnapper repository, hopefully you've found the guide about contributing to WipperSnapper.
Are you planning to write the software driver / code for this component too? We (@brentru and I) will gladly help you with any questions you have, maybe start a draft (draft if you think it's not ready yet) pull request over in the main repository with your first code / thoughts / attempt and we can discuss anything related to the codebase in more detail there.

Apologies for the change in review status, but I think it would make more sense to have raw and raw, with appropriate labels for button and the encoder

Hi @tyeth! Thanks for your message, I've updated definition.json as you requested. It was definitely going to be confusing trying to figure out the difference between unspecified and raw.

Yes, I am going to take a stab at writing the driver, following the instructions on the guide - it looks like I'll just be porting the arduino library to C? I'll create a draft PR if I have any questions. Thanks!

Okay, that's now merged and available in the component picker, but it will have the In-Development banner to warn users that it's functionality/driver is not included in the latest release (or may be unstable/untested).

Previously our component picker had a checkbox to show the In-Development components, but with the new searchable redesign currently all components are initially shown. This will not be the case in the new year so you may need to select dev components as part of the component filtering in the future. You can also search for 'dev' to show all dev components in the picker (you'll notice it also includes the Analog 'Dev'ices ADT7410 component):

Awesome, thanks @tyeth!
