Description
Prevent users from zooming too far in/out and panning too far up/down/left/right.
This will help a lot with the upcoming layers feature in #129 - I originally implemented it in that PR, but have split it out into its own PR to help make the review a little smaller.
Development notes
Unfortunately, the translation extent needs to be recalculated on every zoom tick as it needs access to the current scale integer, to correctly multiply the sidebarWidth by the scale to offset it properly
QA notes
Zoom in/out and pan up/down/left/right
