feat: add stardust behind flag "EXPERIMENTAL.stardust"

This adds support for the stardust protocol behind the flag 
EXPERIMENTAL.stardust

This pr is part of the endeavour to replace ws-star with stardust for 
the time being until a better solution is found.

See the discussion at 
libp2p/js-libp2p-websocket-star#70 (comment) 
for more information
