feat: possibility to pass parameters to a pager

[fffed]

Is there any possibility to pass parameters to a pager?

For example, I would like to scroll a preview window to a line number on opening and I could achieve this with less by running less readme.md +100. Could it be achieved by something like glow readme.md -p +100?

This is a good idea. I've added it as a potential feature.
