Add support for packed clients (#802)

* First iteration of pack reader and interface

* Fix memory leak and remove logs

* Complete packed asset interface and begin on file loading replacement

* Implement proper BinaryIO error

* Improve AssetMemoryBuffer for reading and implement more reading

* Repair more file loading code and improve how navmeshes are loaded

* Missing checks implementation

* Revert addition of Manifest class and migration changes

* Resolved all feedback.
