Description
Feature or enhancement
Proposal:
When the underlying libzstd of compression.zstd encounters an error, compression.zstd only raises a vague "Unable to decompress Zstandard data: Data corruption detected" while libzstd is way more verbose about what actually went wrong, my proposal is to either raise a more descriptive error or expose the raw return code in ZstdError.
Has this already been discussed elsewhere?
This is a minor feature, which does not need previous discussion elsewhere
