Golang interface to LZ4 compression.
Forked from github.com/cloudflare/golz4 but with significant differences:
- input/output arg order has been swapped to follow Go convention, ie
Compress(in, out)->Compress(out, in) - builds against the liblz4 that it detects using pkgconfig

Building golz4 requires that lz4 library be available.
On Debian or Ubuntu, this is as easy as running
$ sudo apt-get install liblz4-dev
On MacOS
$ brew install lz4
If the library version provided for your OS is too old and does not include a liblz4.pc pkg-config file, the upstream documentation describes how to build and install from source.
NOTE: if lz4 is not installed in standard directories, setting PKG_CONFIG_PATH environment variable with the directory containing the liblz4.pc file will help.
