Add std.ArrayList.remove

[daurnimator]

There should be a function std.ArrayList.remove that moves fields down to fill the empty space.

It may be useful to add a backwards iterator at the same time.

Hmm. That's not really advisable for a lot of use cases. It would at least have to have an awkward sounding name.

To be more specific, I need to filter an ArrayList to remove some values. In my case, I already know the indexes of the items to be removed.

We currently only have ArrayList.swapRemove, however I need to retain order.

Maybe orderedRemove or shiftRemove.
In Jai, this is called array_ordered_remove IIRC.

If you were gonna add remove though, I'd default it to swapRemove, for speed.

Maybe that means that I wouldn't add it and just have swapRemove and orderedRemove.

I like orderedRemove.
