[Enhancement Request] Keep zoom level when swiping to new page

[Darker1300]

Currently, when swiping to a new page it resets the zoom level. Please add an option to allow: when swiping left or right to another page, keep the zoom level at its current amount and reset the position to the top-right or top-left corner, as appropriate for the current setting of right-to-left or left-to-right reading.

I think this existed as a feature on a different older iteration of EhViewer, and it was extremely valuable.
