Tobias Geerinckx-Rice cbbd7230ac lz4 129 -> 130
Hotfix, solving issues with lz4cat.

- Fixed: incompatibility sparse mode vs console (#105)
- Fixed: LZ4IO exits too early when frame crc not present (#106)
- Fixed: incompatibility sparse mode vs append mode (#110)
- Performance fix: big compression speed boost for clang (+30%)
- New: cross-version test

longDescription = ''
Very fast lossless compression algorithm, providing compression speed
at 400 MB/s per core, with near-linear scalability for multi-threaded
applications. It also features an extremely fast decoder, with speed in
multiple GB/s per core, typically reaching RAM speed limits on
multi-core systems.
