Compute histogram bin positions beyond length 5000

Fixes #1682

@alexcjohnson does this look acceptable?

[alexcjohnson]

Makes sense, the fix for #484 is going to be very similar. But, like my comment there #484 (comment) I wonder if we still want to have some hard-coded upper bound on the total number, even if it's super high like 1e6?

though I do think we need some sort of upper bound to prevent locking the browser - this can happen easily for example if you specify an explicit tick spacing and then zoom out a lot.

Yeah, a super high upper bound would make sense. Maybe we could put that upper bound somewhere in a constants file and reuse it in all our while loops? Though, locking the browser is less concerning here as this while loop is called in the calc step as opposed to #484 which is called in the plot step.
