Large PRs should have file number next to next/prev buttons

In the above image here, you can see for a huge PR that the Bitbucket PR no longer shows every file, but it moves into "one-at-a-time mode". There's a left and right button for selecting the next or previous file.

The issue is that there is no way to know how far I am through the list.

I ask for a "File 34 of 378" next to the arrows.
