Description

I believe QPackEncoder and QPackDecoder currently only support static header compression.

.NET should support dynamic compression to reduce network traffic and potentially save CPU usage spent encoding/decoding uncompressed header values.

Contributor guide

Research direction
Study the HTTP/3 QPack specification for dynamic table updates, then modify the QPackEncoder and QPackDecoder classes to support dynamic compression. Start by adding a dynamic table data structure and implementing the necessary encoding/decoding logic for dynamic entries.
