[Bug?] Types documentation and implementation mismatch for string#charCodeAt()

[jtenner]

ERROR AS200: Conversion from type 'i32' to 'u16' requires an explicit cast.

       let value: u16 = color.charCodeAt(i);
                        ~~~~~~~~~~~~~~~~~~~
 in assembly/__tests__/ColorParseOperation.spec.ts(8,23)

In the index.d.ts file, it's marked at u16 as I think it should be, but the implementation likely has an i32 output, which is currently unexpected.

declare class String {
  charCodeAt(index: u32): u16;
}

I can't submit a pull request right this second, but if nobody makes it by the end of tonight, I can probably get around to this.

The question is, what needs to be done?

Good catch! Should be i32 everywhere

Thanks for the fix.
