Add async keyword to saving in COMP class

Hi,

with the new stoner rework it’s super nice to have setups for different outputs in a base that is referenced by it, the only downside is, that each time I want to save the configuration I perform a .save() on the component to save it as a tox and due to the textures inside those files get quite big…
for the TOP class there is the keyword async to write the texture in the background, could you add it also for the COMP class?

Thanks!
