Files_Saver

new struct called files_Saver will be used with std::thread and it will
be accepting vectors stack for saving files while still using the
editor... because right now it's taking alot of time to save blendmaps
so i might add single blendmap encoding into PNG then just call it
whenever there's a need to see a new terrain, however i'm looking to do
this for every large function that need external files to be saved
