- Restreamer: it supports restreaming of the video stream to reduce the load on rtsp source
  The restreamer function is designed to reduce the load on the video camera and network channel
  when several/many users are watching a stream.
  IP video cameras typically support a limited number of simultaneous connections.
  A proxy with enabled the restreamer feature will only use one connection to the video camera for all users
  watching the same stream.
  Note: Streams are considered different if their URLs are different.
  By default, the restreamer function is enabled; to disable it, change the following parameter in the ws_rtsp.ini file:
      ---
   enable_restreamer=false
      ---
- support Restreamer in tunnel client
- support h265 stream in tunnel client
- a tunnel search button and an example of configuration between a proxy and a client tunnel were added to the test page
- added a mechanism for monitoring connection loss and automatic recovery, increased stability
 Connection timeout:
 The proxy has the functionality of checking connections using ping messages. This makes sense since, unlike TCP,
 websocket connections remain open when the physical channel is lost. If, due to Internet problems, the message
 about closing the websocket by the other party was not delivered, then the websocket will remain open,
 awaiting incoming messages. To close such websocket connections, the proxy functionality checks the connection status
 based on ping messages.
 Setting parameters for checking the proxy connection -> tunnel is located in ws_rtsp.ini:
      ---
  [Tunnel]
  ping_interval=5
  pong_timeout=1000
      ---
 Configuring parameters for checking the tunnel -> proxy connection is located in rtsp_ws_tunnel_client.ini:
      ---
  ping_interval=5
  pong_timeout=1000
      ---
 Checking the connection status has two parameters:
 ping_interval: Interval for sending ping messages in seconds. Messages will not be sent if 0 seconds is set.
 pong_timeout: Timeout in milliseconds for a pong message in response to a ping message.
 The timer will be disabled if set to 0 milliseconds.
 Configuring proxy connection check parameters -> browser is located in ws_rtsp.ini:
      ---
 ping_interval=5
 pong_timeout=1000
      ---
- Added a script to simplify the test page configuration:
 Linux: setup app , Win: config_app
 allows to change the configuration from localhost to local IP address of PC where the proxy is deployed
