Option to center view on line passed to --highlight-line

[Jlll1]

Currently, when you highlight a line that's beyond the initial range of displayed lines, you need to scroll down to see it. This means that tools that use bat to display search results need to implement additional logic to center the view on the highlighted line. It would be nice to have an option to automatically center the view on the line specified in --highlight-line.

This would require bat to know how to tell whatever pager you are using to scroll. I'm not sure we want to go down that rabbit hole, but #1185 (comment) and #1053 may interest you. Potentially this could also be a use case for plugins (#2203)
