Testing various compression types. Is there anything special that needs to be done to support lz4 export compression?
$ incus export sandbox sandbox.tar.lz4 --instance-only --compression lz4
Error: Fetch instance backup file: Compression algorithm "lz4" isn't currently supported
$ which lz4
/usr/local/bin/lz4
$ lz4 -V
*** lz4 v1.10.0 64-bit multithread, by Yann Collet ***
$ incus --version
