Add // prettier-ignore comments to prevent re-formatting of certain data structures

There's a fair number of (primarily) `Array`s/`TypedArray`s whose formatting we don't want disturb, since in many cases that would lead to the code becoming much more difficult to read and/or break existing inline comments.

*Please note:* It may be a good idea to look through these cases individually, and possibly re-write some of the them (especially the `String` ones) to reduce the need for all of these ignore commands.
