Put predicates into its own module #343
Description
What's needed?
It is likely that with time a few more predicates are added. Since this is very auxiliary to the channels concept, and might not read very obviously under the channels namespace, it might be useful to group them in its own module.
Proposed solution
Add a new module frequenz.channels.experimental.filter_predicates.
