HTTP/2 Priority Tree

Priority is a pure-Python implementation of the HTTP/2 priority logic, as described in RFC 7540 Section 5.3 (Stream Priority). It allows clients to express preferences for how servers allocate resources across concurrent HTTP/2 requests by managing a priority tree. The library uses a variant of the implementation from the H2O project. The current version, 2.0.0, was released in June 2021, indicating a stable project in maintenance mode, part of the broader python-hyper ecosystem for HTTP/2 related libraries.
