Michael Fabian 'Xaymar' Dirks df8ebd94ea filter-displacement: Refactor onto obs::source_factory
This drastically improves stability and prevents all exceptions from leaking into libobs C code, which prevents crashes and unexpected freezes from exception handlers further down the stack.

Additionally minor work was done to further improve the quality and user experience for the filter.
