Description
Problem Statement
Similar to what we have for Redux (https://docs.sentry.io/platforms/javascript/guides/react/configuration/integrations/redux/), it would be nice to have an integration for Mobx.

Solution Brainstorm
- Add breadcrumbs whenever state changes happen
- Output latest state to error context
- Hook into stuff for performance monitoring/error tracking as appropriate
