More cleanup for buffer loading
...
Don't bother with unnecessary and unused converters, and remove some
unsupported queries.

Remove support for (signed) byte and ushort sample storage
...
Also not used without buffer_samples

Unused without the buffer_samples extension

Store mulaw and alaw samples directly in the buffer
...
They're now decompressed on the fly in the mixer. This is not a significant
performance issue given that it only needs a 512-byte lookup table, and the
buffer stores half as much data (it may actually be faster, requiring less
overall memory).

Convert float samples to integer using a power-of-2 multiple

Remove the (u)byte3 sample formats
...
They're not accessible since the removal of the buffer_samples extension, and
were kind of clunky to work with as 24-bit packed values.

Convert integer samples to float using a power-of-2 divisor
...
This should cut down on unnecessary quantization noise (however minor) for 8-
and 16-bit samples. Unfortunately a power-of-2 multiple can't be used as easily
for converting float samples to integer, due to integer types having a non-
power-of-2 maximum amplitude (it'd require more per-sample clamping).
