I added PagedSliverMasonryGrid and rewrote PagedMasonryGrid to use it internally.
To facilitate this change, I moved _AppendedSliverGrid into its own file.
SliverMasonryGrid is very similar to SliverGrid but not the same, so reusing this felt right.
I imagine if we implement other wrappers around the new custom staggered grid view types, this will also come in handy.
All tests pass as usual and I did not add new ones as PagedMasonrySliverGrid is tested through PagedMasonryGridView and I have seen that PagedSliverGrid does not have tests at the moment either.
I have reverted PagedMasonryGridView to a BoxScrollView so that it is consistent with other paged sliver wrappers and can be used with pull_to_refresh.
(code based on provisional code for a masonry grid I added in my own repo)
