   Not for this PR, but at some point - like perhaps, whenever we get around to fully generating __init__.py - this all seems ripe for abstracting into the dash core, like

   _js_dist = _dash.development.list_resources(
       ['bundle.js'],
       ['async~{}.js'.format(resource) for resource in async_resources],
       external_prefix='https://unpkg.com/dash-bio@{}/dash_bio'.format(__version__)
   )

   May still need some tweaking to handle edge cases like async: 'eager'|'lazy', but we should at least be able to auto-detect sourcemaps (which may not exist in release versions #910) and set them all dynamic: True regardless of the resource setting.

   Feels like the end goal is that the metadata just has a list of async_resources - maybe by extension it also has a list of resources (sync), as well as dynamic_resources, eager_resources, and lazy_resources?
