[Feature Request]: Split PDF when total pages count is unknown

[t0mmili]

Feature Description

Split PDF should allow to choose range from x to y, where x is known, and y is unknown (end of document).

Why is this feature valuable?

I was trying to split document, but didn't remember what is the actual pages count (which is often the case). In the Info box there's no information how to do this , In src code I found all, which works, but it's not intuitive, comparing to other similar apps.
