I would like to import py-blake3-1.0.9, which is a RDEP for an update of
sysutils/borgwrapper/2.0. See attachment.

Passes tests on amd64.

COMMENT
Python bindings for the Rust blake3 crate

CATEGORIES

DESCR
Python bindings for the official Rust implementation of BLAKE3, based on
PyO3. These bindings expose all the features of BLAKE3, including
extendable output, keying, and multithreading. The basic API matches
that of Python's standard hashlib module.
