Buffer and Memory Optimizations (#6)

Browse Source 
* Fixes for memory leaks when creating or mapping the contents of a buffer
* Unmap methods on Buffer and Memory objects for required use after utilizing their Map methods
* Optimize MapInfo.WriteData to use memcpy
* Re-implement BufferFromBytes using GBytes and `gst_buffer_new_wrapped_bytes` instead of `gst_buffer_new_wrapped`.
