And put back our magic number, because our bytecode format differs
from upstream
drop btree & framebuf natmods, they had additional problems I didn't
want to fix right now.
this implementation is hoped to be smaller. (feather_m4_express/fr fits
unlike the other PR; approximate savings ~600 bytes)
Minor difference to standard Python: A `dict` object has a
`move_to_end` method. However, calling this method always results in
TypeError.
Implementing it this way means that the method table can still be shared
between OrderedDict and builtin dict.
Closes#4408.
... by the disassembly just below
This was tripped up because in exactly the right conditions some qstr
could be of the form 'xx 63' and make the expression `\.\+63` match
something other than what was intended.
This test was re-worked upstream for mpy version 6 so it'll be a conflict
to resolve when we get to that. :-/
This enables the specific use case of checking whether a note's release
phase has ended, but is also potentially useful to implement a sort of
"voice stealing" algorithm in Python code, which can take account of
the note's envelope state as well as other factors specific to the
program.
skip all the byecode hex data, it's adequately checked

Apply envelope & panning after biquad filtering.
This may fix the weird popping problem. It also reduces the number
of operations that are done "in stereo", so it could help performance.
It also fixes a previously unnoticed problem where a ring-modulated
waveform had 2x the amplitude of an un-modulated waveform.
The test differences look large but it's because some values got changed
in the LSB after the mathematical divisions were moved around.
