Dale Whinham 5d39db9682 Switch FluidSynth to use a custom memory allocator 
Add a Doom-style "zone" memory allocator that can be used instead of
malloc()/realloc()/free() for FluidSynth.

This removes the need to reconfigure the Circle heap and could reduce
fragmentation caused by repeated loading/unloading of SoundFonts.

Dale Whinham f060199032 Temporarily apply FluidSynth upstream patches

patch until a new version is released.

This should clear up some memory leaks related to SoundFont unloading.

Dale Whinham 10e01593a3 Enable High Speed mode for supported SD cards 
An enhancement was recently merged into Circle's develop branch that
increases SD card I/O performance by enabling High Speed mode where
supported (https://github.com/rsta2/circle/pull/174).

Temporarily apply these commits as patches until a new version of Circle
is released.

Dale Whinham 4de13be8f5 Initial support for the Blokas Pisound 
This commit adds a driver for the Blokas Pisound audio/MIDI HAT based on
the Linux sources.

Currently this requires a patch to Circle to allow the Pi's I2S audio
device to operate in slave mode.

The Pisound only works at 48000Hz, 96000Hz, and 192000Hz. The Pisound is
automatically detected by the startup code; the user only has to enable
I2S audio output.

MIDI output and recording functionality is not supported.

Closes #42.

Dale Whinham 7bb3946e49 Disable save/restore floating point registers 
This should no longer be required now that audio rendering happens
outside of an interrupt context.

Dale Whinham c5a4f684b4 Add custom heap configuration for large allocs 
Without this commit, large allocations cannot be freed later on as they
will not fit into the default bucket sizes.

Bucket size values chosen with popular large SoundFonts and the 512MB
Raspberry Pi 3A+ in mind.

This could be replaced with a better memory allocator in future.
