This configuration is used by @ladyada and more often than it should
we've discovered late that a change introduced problems building
there.
By adding this to regular CI, hopefully we learn about and fix these
issues sooner rather than later.
Before, when an OnDiskBitmap was a paletted bitmap type, the palette
was internal to the OnDiskBitmap, and it internally performed the palette
conversion itself. When using with a tilegrid, a ColorConverter() object
always had to be passed.
Now, an OnDiskBitmap has a "pixel_shader" property. If the bitmap is
a paletted bitmap type, it is a (modifiable) Palette object. Otherwise,
it is a ColorConverter() object as before. This allows palette effects
to be applied to paletted OnDiskBitmaps.
Code that used to say:
```python
face = displayio.TileGrid(odb, pixel_shader=displayio.ColorConverter())
```
must be updated to say:
```python
face = displayio.TileGrid(odb, pixel_shader=odb.pixel_shader)
```
Compatible code for 6.x and 7.x can say
```python
face = displayio.TileGrid(odb, pixel_shader=getattr(odb, 'pixel_shader', ColorConverter())
```
With GCC 11 there is now a warning about array bounds of OTP-mac, due to
the OTP being a literal address.

We can't handle rgbmatrix's interrupts from here until the display is
reinitialized, so set the display as paused.
With this change, I can survive multiple cycles with wifi+rgbmatrix
on an esp32s2. Before, it usually failed.
If digest is called then the hash object is put in a "final" state and
calling update() or digest() again will raise a ValueError (instead of
silently producing the wrong result).
See issue #4119.

The 512k build does not have a filesystem so there is no reason to include
the filesystem-related modules. This commit provides a custom manifest.py
for this board which no longer includes: _boot.py, flashbdev.py,
inisetup.py, upip.py, upip_utarfile.py. This cuts the build down by about
9k of flash.

This adds a coverage build and running of the test suite on a MIPS 32-bit
big endian architecture. It uses the feature of qemu to execute foreign
code as though it were native to the system (using qemu user mode). The
code compiled for MIPS will run under the qemu VM, but all syscalls made by
this code go to the host (Linux) system.
See related #7268 and #7273.
