Various test-related fixes

• Fix error where integer coordinates were not properly converted to Double coordinates
• Update test fringe geometries to cover 95% of geometry edge-cases
• When logger is set to trace mode, individually log id/kind of features (with invalid geometries) that are unable to be stored in Ignite
• Increase robustness of tests by doing equality check between cache/featureset now that featureset only stores features with valid geometries
• remove visualization job from CI workflow since it had no effect

Note: Test coverage is now up to 88%!
