Make SevenZArchiveEntry getCompressedSize() public

Please make the compressedSize property of SevenZArchiveEntry as observable property with getter. Having this property as observable, we can know in anytime the compressed size of an entry. Or maybe only a getter to existing compressedSize property.

I've attached two screenshots with both original file size and the compressed size in SevenZArchiveEntry class, running my project in debbug.

Edited: 
I've saw right now that already exists a getCompressedSize() method, but is private. Make that public, to be accessible, please.
