Increase customization options for statistics

[BrentTechDesigns]

Allow for greater customization of the statistics view
Having the statistics available is very helpful, but often displays too much information, and not the desired location. This is a request to allow the statistics view to be moved but also limited to a certain number of data points.

Examples

• Bottom left
  [currently stream quality]
  [latency delay behind streamer]

• Bottom right
  [buffer]
