Update feature table compatibility.

Update compatibility for Canon and Nikon in different connection modes.

Fix connect cancel handling. (#228)

During a failed reconnect, the cancel request was effectively ignored.
Correct this.

Correct Fujifilm GPS day and month ordering. (#227)

Correct the order of day and month in the structure, this appears to
have been wrong from day zero.

Fix GPS updates for FujifilmSecure.

Simplify and correct GPS data handling.

Fix FauxNY connection. (#226)

Appease clang-format.

Fix finding client during disconnect event. (#220)

With target RPA active, addresses change before connection and after
identify resolution.
This resulted in a failure to find the right client handle when
searching by peer address.

Fix this by finding the client by connection handle.

Move test build version logic into workflow.

Leverage the build system and github actions to handle the test version
stuff.

Update M5 libraries. (#218)

Update M5Unified to 0.2.8.
Update M5GFX to 0.2.10.

Fix reconnect after initial pairing.

Further record the pairing state so reconnect immediately after initial
pairing works.
