Match WS events against filters

[gpunto]

Goal

Implement changes to filter WS events locally so we can avoid handling events that don't match filters.

Core PR: GetStream/stream-core-android#14
iOS PR: GetStream/stream-feeds-swift#14

Implementation

• Implement localValue lambda for all filter fields. Note: some are not implemented because the local value doesn't exist
• Added/removed some filter fields based on what the backend actually supports
• Use matches function to filter activity added & updated events

Testing

An example where the effect of local filtering is evident is in the sample when creating a post or a story. Before, either would show up in both the regular timeline and the stories row, while now they only show up the correct place.
