Jeff Epler 57fde2e07b sdcardio: implement new library for SD card I/O
Testing performed: That a card is successfully mounted on Pygamer with
the built in SD card slot

This module is enabled for most FULL_BUILD boards, but is disabled for
samd21 ("M0"), litex, and pca10100 for various reasons.

Jeff Epler a580f0f1c4 _pew: move to common-hal
I noticed that this code was referring to samd-specific functionality,
and isn't enabled except in one samd board (pewpew10).  Move it.

There is incomplte support for _pew in mimxrt10xx which then caused build
errors; adding a #if guard to check for _pew being enabled fixes it.
The _pew module is not likely to be important on mimxrt but I'll leave the
choice to remove it to someone else.

Jeff Epler 0722dafc24 audiomixer: Fix garbled playback when voice 0 is stopped, audio pops
There were two main problems
 - word_buffer was being filled as though with unsigned samples,
   but during mixing all samples are kept in signed mode
 - If the first buffer was stopped, the voices_active flag got set
   anyway, even though the output buffer wasn't initialized yet,
   so the samples were mixed with indeterminate data

We also cover the case where no buffer was playing, and ensure
the output buffer is filled.

This now works much better.  Tested on neotrellis m4 playing back
4 mp3 streams at a time in signed-16, 22050Hz

Use mp_int_t for setting pixelbuf slice indices
When handling negative steps, start and stop need to be mp_int_t so they
can be checked against a potential negative value during the for loop
used to set the slice values.

warriorofwire 4bbb80e31a vectorio: speed up polygon
This change takes polygon from 126k pixels per second fill to 240k pps fill
  on a reference 5 point star 50x66px polygon, updating both location and shape
  at 10hz.  Tested on an m4 express feather.

As a curiosity, the flat-out fill rate of a shape whose get_pixel is `return 0;`
  fills just shy of 375k pixels per second.

warriorofwire 206d0e598a Add vectorio: for drawing shapes
vectorio builds on m4 express feather

Concrete shapes are composed into a VectorShape which is put into a displayio Group for display.

VectorShape provides transpose and x/y positioning for shape implementations.

Included Shapes:

* Circle
  - A radius; Circle is positioned at its axis in the VectorShape.
  - You can freely modify the radius to grow and shrink the circle in-place.

* Polygon
  - An ordered list of points.
  - Beteween each successive point an edge is inferred.  A final edge closing the shape is inferred between the last
    point and the first point.
  - You can modify the points in a Polygon.  The points' coordinate system is relative to (0, 0) so if you'd like a
      top-center justified 10x20 rectangle you can do points [(-5, 0), (5, 0), (5, 20), (0, 20)] and your VectorShape
      x and y properties will position the rectangle relative to its top center point

* Rectangle
  A width and a height.

Sean Cross b168784fa0 aesio: add basic AES encryption and decryption
This adds initial support for an AES module named aesio.  This
implementation supports only a subset of AES modes, namely
ECB, CBC, and CTR modes.

Example usage:

```
>>> import aesio
>>>
>>> key = b'Sixteen byte key'
>>> cipher = aesio.AES(key, aesio.MODE_ECB)
>>> output = bytearray(16)
>>> cipher.encrypt_into(b'Circuit Python!!', output)
>>> output
bytearray(b'E\x14\x85\x18\x9a\x9c\r\x95>\xa7kV\xa2`\x8b\n')
>>>
```

This key is 16-bytes, so it uses AES128.  If your key is 24- or 32-
bytes long, it will switch to AES192 or AES256 respectively.

This has been tested with many of the official NIST test vectors,
such as those used in `pycryptodome` at
39626a5b01/lib/Crypto/SelfTest/Cipher/test_vectors/AES

CTR has not been tested as NIST does not provide test vectors for it.

This gets all the purely internal references.  Some uses of
