COMPRESS-405 Create Fixed Length Block OutputStream / WriteableByteChannel
This PR provides a new class that is an OutputStream and
WritableByteChannel, and which supports writing to a destination output stream
or byte channel in fixed size blocks. Internally, all writes are made using NIO.
If the destination is a FileOutputStream the existing channel is used.
Other OutputStreams are wrapped with a custom channel implementation which
does not attempt to split writes into chunks.
If the target channel fails to write the entire buffer in a single call, an
exception is thrown,
Incoming data is accumulated in a ByteBuffer until a complete block is
ready, then written to the target.
If WritableByteChannel::write(ByteBuffer) method is called, the code will
attempt to avoid copying data into the buffer if the buffer is empty, and a
complete block is available.
**The class and UnitTest are in compress/utils . This is a MINOR change -
thus the version number for the package should be increated to 1.15.0**
