RFC: streaming-bytestring dropping support for GHC 7

Hi! We the maintainers of the streaming-bytestring package intend to officially drop support for GHC 7. A new major version (0.3) would be cut to reflect this. The library is otherwise stable; it is not actively developed.

If you would be disproportionately affected by this and are for some reason unable to stay on the 0.2 series, please contact us here or on the linked issue above. Thanks!
