Resolves #393 - Adds support for recording demodulated (raw) bitstream
...
buffers. None of the decoders currently support this yet, but the P25
will be updated to provide bitstream output for recording.
Renames the ReusableBuffer class to ReusableFloatBuffer for
consistency.

[WIP] Implements reusable sample buffers across all components. This
...
produces a significant reduction in memory usage, especially for tuners
like the airspy and hackrf that produce 10/20 MSPS sample rates. This
is observed to be around 66% reduction in peak memory usage and provides
a more stable memory utilization across time reducing stress on the
garbage collector.
Use of these reusable memory buffers will be pushed further down into
the processing chain modules to ensure we keep new object creation
to the lowest levels possible.
