Do not use lookup tables for put_image_data

Fixes #9599

"This is the first Rust code I have ever written" (and also my first time writing real browser code, it's been quite the learning experience).

Some questions:

> For really fast CPU results, use integer SIMD instructions to handle more than one pixel at a time.

This was out of the scope of #9599, right? I started looking into doing that, but it seems to be a lot more work than the `E-easy` label would suggest. [`std::simd`](https://doc.rust-lang.org/1.0.0/std/simd/index.html) is marked as "unstable", is that a blocker?

> 128 can be added before dividing to round more accurately.

@michaelwu, what did you mean by that?

Also, the #9599 is `Do not use lookup tables for {Get,Put}ImageData operations`, but we only use lookup tables for the `Put`, not the `Get`, right?

Sorry for all the noobish questions.
