Unrar of a byte array - Githubissues

Hi,

I did not find a buit-in way of unrar'ing a byte array, so I wrote an implementation of VolumeManager and one of Volume, called ByteArrayVolumeManager and ByteArrayVolume.

I think they may be useful to someone else, so I donate them to the project ;-)

I ask you, anyway, to check that I did not do any large and stupid error (my tests are ok, though).

I paste them here:
