Bugfix: Update zstd library to fix possible data corruption at max. compression
In restic 0.16.0, backups using maximum compression could result in data
corruption due to a bug in the library used for compressing data. Please note
that the "auto" compression level (used by default) is not affected!
To check a repository for data corruption, run `restic check --read-data`. This
will download and verify the whole repository. If the `check` command detects
data corruption, follow the suggested steps. To simplify the repository repair
and minimize data loss, we've also added an experimental `repair packs` command
that salvages all valid data from the affected pack files.
Restic now uses the latest version of the library used to compress data, which
includes a fix for the data corruption issue.
