These two classes are fundamental to basic HTTP usage, but specifically need to be implemented to allow PHP.Gt/Fetch to reach its next stable release. PhpGt/Fetch#99 relies on this issue. Class list to implement: - [x] [FormData](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/FormData) - [x] [URLSearchParams](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/URLSearchParams) - [x] [TypedArray](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/TypedArray) - [x] ~~[DataView](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/DataView)~~ not supported for PHP (I think...) - [x] [Blob](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Blob) - [x] FileUpload (or similarly named class)
