As5600

[tyeth]

Adds the magnetic angle sensor.
Worth noting the device zeros on reset/init.

Not sure my angular calculation from the "scaled" value correctly gives 0-359 which I think is what's expected.
Also didn't have a great magnet for testing, but did see rotation, and returning to approximate expected angle

Note to self - Do not merge without testing reinitialising the as5600

@tyeth Requesting two changes

[tyeth]

As mentioned in the MLX pull request, I believe (not verified 100%) the destructors are not being called, due to the delete *iter line being disabled:
https://github.com/adafruit/Adafruit_Wippersnapper_Arduino/blob/main/src/components/i2c/WipperSnapper_I2C.cpp#L1038
I only say that due to having the delete in there with an if check first plus set to nullptr, but it still crashed - now in actual fact that may have been due to testing reinitialisation too where the main adafruit_mlx driver didn't yet have the i2c_dev=nullptr fix applied that I later locally applied in testing.
I should verify if the destructors are being called, presumably by the erase_ later in the same code block of wipper_i2c.cpp

@tyeth MLX has been fixed and released, is this PR still blocking?
