Update kernel latitude (#372)

* scale kernel to account for geographic projection

* scaling gaussian filter with latitude

* updating distance calc

* adding assert statement about size of filter

* Refactor haversine function and enhance grid spacing info extraction; update tests for weight generation and add new tests for elliptical kernel generation

* Fix weight generation logic by correcting filter coordinate range and enhancing assertions for non-zero pixel counts

* Enhance pixel count validation in fire kernel generation and update symmetry tests

- Added assertions to validate the number of non-zero pixels in the generated weights for fire ellipse kernels, ensuring they fall within a calculated range based on expected pixel counts.
- Updated test cases for kernel symmetry to check for approximate equality in pixel counts rather than strict equality, accommodating for potential discrepancies due to discrete grid offsets.

* Add output logging for kernel normalization, latitude dependence, and symmetry tests
