Paging currently supports collecting Flow<PagingData> from non-main thread, which is useful for controlling the context in which all of Paging's initialization and object creation happens. It also control the default context for transforms, since that is applied on the internal Flow<PageEvent> which is collected from call to .submitData().

Unfortunately, collecting PagingData and calling .submitData all happen internally in paging-compose so there is no way to control this behavior if using LazyPagingItems.

Ideally we can make the context configurable, but if not we should at least have a more sane default.
