Description
PyProj has this area_of_use CRS property:
https://pyproj4.github.io/pyproj/stable/api/crs/crs.html#pyproj.crs.CRS.area_of_use
It allows to check if a certain extent it within the valid bounds of the CRS, so exceptions can be avoided.
This is quite relevant when dealing with rasters that are larger then the valid area of a CRS. We for instance could use it here:
https://github.com/locationtech/geotrellis/pull/3542

Research direction
Start by reviewing the proj4j CRS-related APIs and the linked PyProj area_of_use documentation, then compare the referenced Geotrellis use case. Done means proj4j exposes equivalent CRS area-of-use information so callers can check whether an extent falls within valid bounds; the issue does not name a file or test.
