Implemented LZMA frame encoder

Motivation:

LZMA compression algorithm has a very good compression ratio.

Modifications:

- Added `lzma-java` library which implements LZMA algorithm.
- Implemented `LzmaFrameEncoder` which extends `MessageToByteEncoder` and provides compression of outgoing messages.
- Added tests to verify the `LzmaFrameEncoder` and how it can compress data for the next uncompression using the original library.

Result:

LZMA encoder which can compress data using LZMA algorithm.

I know we not do anything useful in our close() methods of the streams at the moment but maybe you should call bbIn.close() and bbOut.close() anyway just to be safe in the future ?
