      Description

      Addition of the zstd compression standard to erofs.

      This requires support in the userland utils for creating filesystems images, and also kernel support. The zstd compression standard supports a dictionary mode which, if it is easier could be added as an extra after the basic support has been included. I suspect it may be easier to implement in two stages.
