get Huffman Codec Provider
Gets the Huffman codec provider. This is implemented in a provider format to allow the server to use blocking implementations, which allow lazy-loading Huffman. This is useful to allow binding the network early on in the boot cycle without having to wait behind Huffman. If a blocking implementation is used, and Huffman isn't ready when it is needed, the underlying Netty thread will be blocked until it is supplied. Because of this, it is recommended to use the non-blocking variant in production.
