Allow rpaks to use starpaks that are in the mod's folder (#279)v1.10.0-rc4

* this works

* read starpak entires from rpak headers

* formatting

* move logging to after function

* Use str.empty instead of str != ""

* change allocatedNewPath to std::string

* merge conflict resolution part 2

* change to use int + add comment

* better comments + init variable

* path syntax + another comment

* use goto to exit loop + improve commenting

* implement requested changes

* remove accidental diff

* explanatory comment
