Improve handling of invalid SHX index files

Description
Occasionally a SHP data set includes an invalid shape index file (SHX), and the SHP provider doesn't handle it gracefully. For example, a wrong offset in the SHX can result in a bad invalid content length, and when the provider tries to allocate memory for that content bad things can happen.
A workaround for customers is to delete the SHX file, but we can also make the provider a little more robust.
