feat: make chats virtualized (#330)

## Motivation

This feature aims to increase the performance in long chats

- uses react-virtualized to render virtual chat history
- requires hacking the overflow of react-virtualized
- requires determinate/fixed heights of images (should in future be
delivered by images, is now hardcoded)
