Verto.newCall() permits passing custom callback functions per call that
override the default dialog callbacks inherited from the Verto object.
However, they are currently set after calling the invite() function, and it's
possible that some of these callbacks could be called during the invite()
function's execution.

To avoid a race condition, move setting these custom callbacks on the dialog
to happen before calling invite().

  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"
  />
