Subject: [PATCH] Fix to allow import/use module from any folder

Load the shared library "ice_secp256k1.dll" or "ice_secp256k1.so" located in the same directory as the python module. By this fix the user can import the module from *ANY* directory using Python's CLI or IDE. Without this fix, the user can only import the module if the current working directory is the directory of this module.
