Add aliases to parser

[lazaray]

This PR fixes some small inconsistencies in the parser and adds support for aliases.

JSON example output:

  "aliases": [
    {
      "type": "Vector4",
      "name": "Quaternion",
      "description": "Quaternion, 4 components (Vector4 alias)"
    },
    {
      "type": "Texture",
      "name": "Texture2D",
      "description": "Texture2D, same as Texture"
    },
    {
      "type": "Texture",
      "name": "TextureCubemap",
      "description": "TextureCubemap, same as Texture"
    },
    {
      "type": "RenderTexture",
      "name": "RenderTexture2D",
      "description": "RenderTexture2D, same as RenderTexture"
    },
    {
      "type": "Camera3D",
      "name": "Camera",
      "description": "Camera type fallback, defaults to Camera3D"
    }
  ],

Thanks a lot for adding this 👍

I've added a fix for fields that share a line, like Matrix.

Matrix now looks like this:

    {
      "name": "Matrix",
      "description": "Matrix, 4x4 components, column major, OpenGL style, right handed",
      "fields": [
        {
          "type": "float",
          "name": "m0",
          "description": "Matrix first row (4 components)"
        },
        {
          "type": "float",
          "name": "m4",
          "description": "Matrix first row (4 components)"
        },
        {
          "type": "float",
          "name": "m8",
          "description": "Matrix first row (4 components)"
        },
        {
          "type": "float",
          "name": "m12",
          "description": "Matrix first row (4 components)"
        },
        {
          "type": "float",
          "name": "m1",
          "description": "Matrix second row (4 components)"
        },
        {
          "type": "float",
          "name": "m5",
          "description": "Matrix second row (4 components)"
        },
        {
          "type": "float",
          "name": "m9",
          "description": "Matrix second row (4 components)"
        },
        {
          "type": "float",
          "name": "m13",
          "description": "Matrix second row (4 components)"
        },
        {
          "type": "float",
          "name": "m2",
          "description": "Matrix third row (4 components)"
        },
        {
          "type": "float",
          "name": "m6",
          "description": "Matrix third row (4 components)"
        },
        {
          "type": "float",
          "name": "m10",
          "description": "Matrix third row (4 components)"
        },
        {
          "type": "float",
          "name": "m14",
          "description": "Matrix third row (4 components)"
        },
        {
          "type": "float",
          "name": "m3",
          "description": "Matrix fourth row (4 components)"
        },

          "name": "m7",
          "description": "Matrix fourth row (4 components)"
        },
        {
          "type": "float",
          "name": "m11",
          "description": "Matrix fourth row (4 components)"
        },
        {
          "type": "float",
          "name": "m15",
          "description": "Matrix fourth row (4 components)"
        }
      ]
    },

Sorry for the force push, I missed one line while manually linting.
