Copy and clean up test.py to main.py. Add app module (currently on
app.py, maybe make it a directory later) for application classes.
Implement app.TimerManager to allow scheduling of delayed events in the
micropython async framework.
Implement app.TagPlaybackManager which handles playing back MP3 files
based on the NFC tag reader. Currently, simply plays all MP3 files in a
folder, for which the folder name matches the tag id, in order. Resume,
random and other features not yet supported.

The python and C modules that are supposed to be built into the firmware
image (i.e. those that are in manifest.py or in USER_C_MODULES) have
been moved to the software/modules directory.
The software/src directory should now only contain python scripts and
other files that should be installed to the Picos flash filesystem. The
idea is that these should be those scripts that implement the
application behaviour, as these are the ones that a user who does not
want to build the whole firmware themself wants to modify.

audiocore: Add async support
...
Rename the exising audiocore C module to _audiocore and create a new
Micropython wrapper module audiocore. This makes it easier to implement
async methods.
Add interrupt support to _audiocore that notifies core0 whenever data
has been consumed from the MP3 bitstream buffer.
Use this interrupt and an asyncio.ThreadSafeFlag to implement
audiocore.async_put which will play back the provided buffer, allowing
other async tasks to run while waiting for space in the bitstream
buffer.

- Use SD_SECTOR_SIZE define instead of magic number 512
- Replace uint8_t buf[1] with plain uint8_t
- Check sd_spi_read_dma precondition that sd_dma_context state has to be
DMA_IDLE explicitly and return false instead of relying on assert

Not as async as possible, and definately needs a future revisit. But
works for now, with acceptable delays, if the newly introduced
