Some small tweaks to the zipfile zstd support added in #133365

  • Add ZIP_ZSTANDARD constant to the module's __all__
  • Add zstd notes to the ZipFile's docstring.
  • Add a missing check for min_level in _write_end_record
  • Pass through the specified compresslevel into the ZstdCompressor and document it.

Note: I didn't create an issue because this all seems fairly trivial, but I can if needed.

Thanks, these changes look good! I had a few minor suggestions. I think we should be careful how we document the accepted values for zstd's compression level. I don't think we can or should hardcode the values, but I also think giving a pointer to where the current values can be found would be useful.

All requested changes applied. I see a test failed, but as far as I can tell it's not related to the changes in this PR.
