snowflake proxy README includes an old version of ./proxy --help

In snowflake/proxy/README, we have this section:

The Snowflake proxy can be run with the following options:

Usage of ./proxy:
  -broker string
        broker URL (default "https://snowflake-broker.torproject.net/")
  -capacity uint
        maximum concurrent clients
  -keep-local-addresses
        keep local LAN address ICE candidates
  -log string
        log filename
  -relay string
        websocket relay URL (default "wss://snowflake.torproject.net/")
  -stun string
        stun URL (default "stun:stun.stunprotocol.org:3478")
  -unsafe-logging
        prevent logs from being scrubbed

but ./proxy --help now shows more options than that:

Usage of ./proxy:
  -allow-non-tls-relay
        allow relay without tls encryption
  -allowed-relay-hostname-pattern string
        a pattern to specify allowed hostname pattern for relay URL. (default "snowflake.torproject.net$")
  -broker string
        broker URL (default "https://snowflake-broker.torproject.net/")
  -capacity uint
        maximum concurrent clients
  -ephemeral-ports-range string
        ICE UDP ephemeral ports range (format:"<min>:<max>")
  -keep-local-addresses
        keep local LAN address ICE candidates
  -log string
        log filename
  -nat-retest-interval duration
        the time interval in second before NAT type is retested, 0s disables retest. Valid time units are "s", "m", "h".  (default 24h0m0s)
  -relay string
        websocket relay URL (default "wss://snowflake.bamsoftware.com/")
  -stun string
        STUN URL (default "stun:stun.stunprotocol.org:3478")
  -summary-interval duration
        the time interval to output summary, 0s disables summaries. Valid time units are "s", "m", "h".  (default 1h0m0s)   
  -unsafe-logging
        prevent logs from being scrubbed
  -verbose
        increase log verbosity

The really simple fix would be to update the README with the newer text. The more robust approach would be to stop trying to maintain the same data in both places (because it's clearly not working), and change the README to teach you how to run ./proxy --help to get the usage, and/or change it to list just the most important options.
