        Add some default session settings: set some assemblies/tracks on/off

        This allows to select a default view:
        - jb type (Linear, Circular, etc)
        - default location on an assembly
        - default tracks
        - ...

        Different methods to do that were tested/discussed:
        - using a defaultSession item in config.json: this proved to be difficult:
          forced to write a full session block, including hard-coded/hard-to-guess items,
          no good way to let Jbrowse2 display a scaffold without knowing its size
        - using JBrowse2 as an embedded React component in a tool-generated html file:
          it works but it requires generating js code to actually do what we want = chosing default view, assembly, tracks, ...
        - writing a session-spec inside the config.json file: this is not yet supported as of 2.10.2 (see PR 4148 below)
          a session-spec is a kind of simplified defaultSession where you don't need to specify every aspect of the session
        - passing a session-spec through URL params by embedding the JBrowse2 index.html inside an iframe
          we selected this option
