Changes since v1:
- Addressed build failures on certain platforms
- Rewrote format handling code to support different sized fields
- Rewrote noop cases to be more robust and efficient
- Add extra paratemer validation for incoming frames
- Various other minor/cosmetic fixes
Of note, this version leverages the graph dispatch mechanism to get free
multi-threaded memcpy in the noop case with preallocated / non-refcounted
buffers. This results in another ~400% speedup for 1:1 scaling on my end.
