Subject: [PATCH 01/15] Use established KEYWORD_TOKENTYPE for Wire keyword

All the other platform bundled libraries use `KEYWORD1` for the library's global instance so this provides consistency.

Subject: [PATCH 02/15] Update action versions used in CI workflows

The "smoke test" sketch compilation and reporting actions have been moved to dedicated repositories. The actions hosted
at the old `arduino/actions/libraries/*` location will no longer be maintained.

Since the time the actions were migrated to the dedicated repositories, a breaking change was made to the default value
of the `sketches-report-path` input, which required a change to the values of the `name` and `path` inputs of the
`actions/upload-artifact` action.

Subject: [PATCH 03/15] Specify sketches report input values for sketch
 compilation CI actions

The reliance on the `actions/upload-artifacts` action as the transfer mechanism between workflow runs means that these
values will always be hardcoded into the workflow. The result is that if the default values of the inputs are changed, it
breaks the workflow, even if the changes are synchronized. So it's more robust to avoid dependening on the default
values.

Subject: [PATCH 04/15] Disable verbose output in sketch compilation CI logs

The `arduino/compile-sketches` action was previously configured for verbose output.. This option is primarily intended to be used for troubleshooting and doesn't contain any information of value for general usage.

Due to the extensive coverage of this CI workflow, the logs are massive, which makes it inconvenient for anyone to read them to identify the cause of a failure. Removing the verbose output will improve that situation

Subject: [PATCH 05/15] Add "smoke test" sketch compilation CI workflow for
 MuxTO firmware

On every push and pull request that affects relevant files, and periodically, compile the Nano Every's MuxTO firmware sketch.

The binary is saved as a workflow artifact to make it available for beta testers who might prefer flashing it directly
over setting up the toolchain needed to compile it locally.

Due to the standard output from Arduino CLI not providing the correct size data, a bespoke check is done for whether the
compiled binary will fit in the available 12 kB of memory. If not, the workflow run fails.

On creation or commit to a pull request, a report of the resulting change in memory usage of the sketch will be
commented to the PR thread.

Subject: [PATCH 06/15] Remove unnecessary HID library

The library was inherited from the "Arduino AVR Boards" platform that was the model for this project. It is used by the ATmega32U4-based boards of Arduino AVR Boards, however this platform's boards do not have a native HID capability and so the library serves no purpose, and in fact will not even compile for this platform's boards. So it will be best to remove it.
