Redundant import of analogio in example.
Confused MagTag user. MagTag does not come with analogio in uf2 and cannot play native WAV with buzzer hardware.
Initially enabled for samd51, this enables reading raw flux data as well
as DOS/MFM formatted media.
This is only the low-level code for reading & decoding flux pulses from a floppy drive.
high level details will live in a Python library.
adafruit-circuitpython-floppy will take care of details like stepping
from track to track, etc.
The port is free to return NULL for any/all of these, and the caller has
to check.
This will be used in the floppy code, because aside from getting the
registers, it looks like all is independent of MCU.
In my testing, there is no way to accurately know how far into a MP3 file
you're currently playing. You can use monotonic time, but that can have
drift versus the audio playback system, which may not be running at exactly
the expected sample rate.
To allow syncing animation with timestamps in a MP3 file, this presents a
new property, decoded_samples, that records the number of audio samples
sent out of the decoder. While this may not be a completely accurate time,
due to mixer delays, it's much better position that the monotonic clock
difference.
Implementation is keeping track of this value in the mp3file structure and
adding to it whenever data is sent out of the decoder. The property
implementation was a copy/paste from current properties in the audiomp3
files.
new utility function for all vectorio shape specializations for testing
whether a screen-space x,y point falls within a shape's x,y.
This respects the current orientation of the screen in the manner of
displayio and vectorio - so your x,y requests are in the same coordinate
domain as your x,y locations and your width/height etc. properties that
ou set on other shapes. I.e., if you're using this for touch points then
you will need to make sure the touch events are in the same x,y domain as
your display.

This helps provide low overhead introspection of shape coverage on screen.
It's envisioned that this will be used for things like touch-and-drag
widget controls, touch "areas" and may help with random ornament placement
on toy Christmas trees.
