There are several default window settings in transport.go:

    // transportDefaultConnFlow is how many connection-level flow control
    // tokens we give the server at start-up, past the default 64k.
    transportDefaultConnFlow = 1 << 30

    // transportDefaultStreamFlow is how many stream-level flow
    // control tokens we announce to the peer, and how many bytes
    // we buffer per stream.
    transportDefaultStreamFlow = 4 << 20

    // transportDefaultStreamMinRefresh is the minimum number of bytes we'll send
    // a stream-level WINDOW_UPDATE for at a time.
    transportDefaultStreamMinRefresh = 4 << 10

NewClientConn method will use these without looking up other places. However, these default values are not suitable for all situations like high-latency high-throughput network.

Can you provide some setters to change these values instead of rewrite the whole thing using Framer or forking and rewriting this repo?
