> LZO is a lossless data compression algorithm which is focused on compression
> and decompression speeds.
> This will enable Apache Beam sdk to compress/decompress files using LZO
> compression algorithm.
> This will include the following functionalities:
> # compress() : for compressing files into an LZO archive
> # decompress() : for decompressing files archived using LZO compression
> Appropriate Input and Output stream will also be added to enable working with
> LZO files.
