* feat(responsive-ui): Keep aspect ratio for filmstrip self view on mobile web

Right now filmstrip displays self view in landscape mode.
With these changes the aspect ratio of the self view will be maintained
so on portrait mode the thumbnail will be displayed vertically.
Of course this makes sense only on mobile web.

* Code review

* Fix height

Ref: https://github.com/oblador/react-native-performance

* send dominant speaker stats

* fix lint

Use a FlatList to avoid loading all participants at once.

- Remove unicode charcters from filenames
- Simplify code for copying them to the iOS SDK

viewableItems always comes in order and indexes are always ascending. In
addition, if the array comes empty (I saw it happen on Android at least, when
scrolling like a maniac) we'd calculate the right value, instead of Infinity.

An item won't be considered visible until it has been visible for 500ms.

When joining a large meeting every participant join would trigger an attempt of
an update. Try to minimize the amount of calls.

interfaceConfig does not exist.

Fixes a React warning

On mobile Safari, when a user joins both audio and video muted, browser doesn't playout the remote audio because of a webkit bug. As a workaround, always add the audio track to peerconnection and then mute the track if needed.
