PackedByteArray to Data helper function

[migueldeicaza]

Currently, I do not expose a "pointer to the array" feature, I could either expose that, or even better, expose a function that returns the Data() for it.

@migueldeicaza I believe this was done in https://github.com/migueldeicaza/SwiftGodot/commit/39c67bf8f4f266802010fc2092d513d7918876c4 But maybe it would make more sense to expose a helper function that returns a byte array instead, without introducing SwiftGodot's dependency on Foundation?

Yes, let us do that for now

Even better, we could surface a withUnsafeAccess helper method that gives us the pointer and addrsss, so folks can do their own data wrapper easily without copying the daya

Closing, implemented alternative without Foundation dependency.
