To support pickling
Warning: This method assumes that the constructor should be defined:
__init__(self, config, version=defaultVersion)
The use of 'config' is effectively set by the registry mechanism.
If additional optional arguments are added, this method should be
overridden to correspond.

Find tracts and patches that overlap a region

@return list of (TractInfo, list of PatchInfo) for tracts and patches that contain,
or may contain, the specified region. The list will be empty if there is no overlap.
@warning this uses a naive algorithm that may find some tracts and patches that do not overlap
the region (especially if the region is not a rectangle aligned along patch x,y).

Return a SHA1 hash that uniquely identifies this SkyMap instance.
Returns
-------
sha1 : bytes
A 20-byte hash that uniquely identifies this SkyMap instance.
Subclasses should almost always override `updateSha1()` instead of
this function to add subclass-specific state to the hash.
