This patch adds an onRemoteStream callback, which can be specified on the Verto
instance, or per dialog. The callback is fired when the remote stream from a
call is received, and receives two arguments, the first is the remote stream,
the second is the Verto dialog object.

  FS-10554: Refactor conference vid-res-id command, add 'force' option

The 'conference vid-res-id' sub command previously used the CONF_API_SUB_MEMBER_TARGET
command parsing strategy. The standard options exposed by that strategy didn't make
sense for this sub command, so it's now been switched to use the CONF_API_SUB_ARGS_SPLIT
command parsing strategy.

A third, optional 'force' argument has also been added. The default behavior of the
command is to toggle the user in and out of a reservation slot, use the force argument
to ensure the user is placed into the reservation slot provided.

The new signature of the sub command is:

  vid-res-id <member_id> <val>|clear [force]

Previously, the font_scale parameter available for the video_mute_banner/video_banner_text
conference channel variable would only accept integer values. It now can accept float
values for more fine grained control, eg:

  <action
    application="set"
    data="video_banner_text={font_scale=.75}Banner Text"
  />

Add params to set min_font_size and max_font_size for video banners.

The hard-coded defaults of 5/24 for min/max font size don't always look good
depending on the layout use case. This adds min_font_size and max_font_size
params for more fine-grained control, eg:

  <action
    application="set"
    data="video_banner_text={min_font_size=8,max_font_size=14}Banner Text"
  />
