Add raymath and raygui support through the new Parser

[RobLoach]

Given that the parser has changed, and it's difficult for us to target different versions of the API vs parser version, it may be worth it to manage it ourselves. The provided raylib_api.json was built using the latest Parser Generator from master, with the 4.0.0 raylib.h.

DO NOT MERGE YET! It's not compiling with this yet. We'll need to wrap...

• float[4]
• char[32]
• Matrix[2]
• float[2]
• float[16]
• Aliases

Fixes #145

[RobLoach]

Need to fix porting the array types.

so I tried to do some work on this front - but ended up throwing out the changes. my understanding of types there was a little wrong. looking at the structs in question - i don't see a need to implicitly cast to/from a JS array anywhere for these unless a user really wanted to manipulate this data manually. I think we can get by with simply casting the pointers for these types into uint64_t, and then (float[]) or what the proper syntax might be on the way into C++.
for Matrix/Vector3V - can these just be implemented in JS? or does raylib do anything extra under the hood when making these?

[RobLoach]

Maybe be difficult to handle directly through the generator. We could likely put together wrapper functions for them though. Similar to the Shader ones you did.

Arrays can be passed by value as arrays in C++, but returned as pointers. Certainly not the best.

Could we do it in js wrapper-space? Like how ref-array-napi does it?

I'm not sure I totally follow what changes are being made and what is failing, but I'd like to help. Is the issue that the generated code uses uintptr_t which is 64bit, but char is 8 bits? Is this what is intended? If this is what we intend, can we just do a cast there?

[konsumer]

I got it to build by hand-editing this:

inline BoneInfo BoneInfoFromValue(const Napi::CallbackInfo& info, int index) {
  return {
     (char) pointerFromValue(info, index + 0),
     charFromValue(info, index + 1)
  };
}

instead of

inline BoneInfo BoneInfoFromValue(const Napi::CallbackInfo& info, int index) {
  return {
     pointerFromValue(info, index + 0),
     charFromValue(info, index + 1)
  };
}

Not sure if that will actually work right, but might lead to a solution.

I added a small change that gets it building in a542777 but I'm really not sure if that is the right way to go. Seems like it probly isn't dealing with arrays right, but I'm not sure how to test it.
