Merging RUM-611 "update-readme" into 'update-version' (the branch it came from)
Changes:
Updates the README to document the API thoroughly for the raygun4reactnative sdk
Adds Breadcrumbs and RaygunStackFrame types to the export list (as these objects can be edited in the BeforeSendCrashReport method)
Removes all instances of "RealUserMonitoringTimings.ViewLoaded | RealUserMonitoringTimings.NetworkCall" as the RealUserMonitoringTimings has now become it's own type with those options being the only enum definitions. Thus, stating that some object must be either or of the only options available, it's unnecessary.
