Added some upper limits on dependencies.

Pandas 2.0 disallows some indexing operations that ginput currently
relies on, so we have to limit Pandas to < 2.0. That then means we need
to limit numpy to < 2.0.0, or we get binary incompatibilities. Then I
decided to limit scipy and netCDF just to be safe.
