Devolay Release v1.2.0

This is a big one! :)

Changelog:

• Removed dependency on boost libraries
• Added a #freeBuffer method on frames to free any Devolay-allocated buffers
• Frames are now automatically freed before receiving, so no more closing and reallocating to receive!
• Added support for the interleaved_32f audio format
• Added conversion methods between float planar, float interleaved, 16s, and 32s audio formats.
• Added frame-sync support
