PyCurious: A Python module for computing the Curie depth from the magnetic anomaly

Formal release after JOSS review. This version of PyCurious implements the following functionality: Anaconda installation support (and fixes for Cython build issues) Checking if windows that exceed the extent of the domain Correct propagation of errors with Tanaka et al. 1999 approach Refactor code to compute the radial power spectrum Updated Docstrings and Jupyter notebooks Updated test suite (using pytest) to test for expected functionality of core routines PEP8 compliant code Depreciated functions: 'CurieGrid.radial_spectrum_log'; instead use 'CurieGrid.radial_spectrum' and pass the argument 'power=0.5' for the same functionality
