03274a5b95 Ensure at least the specified ringbuffer size is writable 
Previously, all but one of the specified size could be written (so for a size
of n, only n-1 was guaranteed writable). All users pretty much compensated for
this, but it makes more sense to fix it at the source.

b5b3ea95f8 Add a config to output first-, second-, or third-order ambisonics 
Currently incomplete, as second- and third-order output will not correctly
handle B-Format input buffers. A standalone up-sampler will be needed, similar
to the high-quality decoder.

Also, output is ACN ordering with SN3D normalization. A config option will
eventually be provided to change this if desired.

6d4380a48c Change the backend getLatency method to return the clock time too 
This will also allow backends to better synchronize the tracked clock time with
the device output latency, without necessarily needing to lock if the backend
API can allow for it.

70fbc2b1ff Add a function to get a list of data files 
The method takes a marked-up filename (e.g. may include %r for a sample rate,
%% for %, etc), and returns a vector of strings of found filenames that match.
It will search the CWD, the local, and global data directories, in that order.

87f3babe2c Append "on OpenAL Soft" to mmdevapi, dsound, and winmm device names 
Would be nicer to have a more backend-agnostic method of doing this, Perhaps
even also only when the router is being used.

0051a96376 Fix 5.1 surround sound 
Apparently, 5.1 surround sound is supposed to use the "side" channels, not the
back channels, and we've been wrong this whole time. That means the "5.1 Side"
is actually the correct 5.1 setup, and using the back channels is anomalous.

Additionally, this means the 5.1 buffer format should also use the the side
channels instead of the back channels.

A final note: the 5.1 mixing coefficients are changed so both use the original
5.1 surround sound set (with the surround channels at +/-110 degrees). So the
only difference now between 5.1 "side" and 5.1 "back" is the channel labels.
