60: Improve BufferedData Performance

[artemananiev]

Fix summary:

• Two subclasses of BufferedData are provided: ByteArrayBufferedData and DirectBufferedData
• Byte array version uses System.arraycopy() to get / read / write bytes
• Direct version uses UnsafeUtils methods to get / read / write bytes
• A new BufferedData level JMH benchmark is provided
• New unit tests are provided for the two new subclasses
• A couple unit tests which were specific to Bytes are made generic, so they are applicable to other random access data implementations, including BufferedData and its subclasses

Fixes: #60
