Would prefer to see NetworkDetails | null where nullable.

Thanks for these changes. This should be helpful for anyone using the default loaders, and for improving internal type safety.

In a situation where someone provides their own loader via config.loader (or pLoader or fLoader) and they want to provide their own struct to networkDetails I wonder how using the project type exports will impact them.

That is a good point, perhaps I need to expand the callback interface to be expressed with some generics and have the default argument be NetworkDetails here.

Another option is to keep the current definition and say that a pLoader or fLoader must return one of these 3 types, in case we ever need to manipulate it internally we can have a verified interface versus a generic (that we can never verify like that), and they can cast Response | XMLHttpRequest to their custom struct in their provided callback and outside of the hls.js internals
