I noticed a lot of comments for existing code, that seem a bit verbose to me. Would you mind removing them, since the code is pretty self-documenting?

did you choose to do it like this because the RealField and ComplexField traits don't expose an is_nan?

Summary of Changes
This PR fixes the issue where the program would panic when encountering NaN elements. I tweaked the
try_new_ordered()function to address NaN values accordingly.Details
try_new_ordered()function to handle NaN values gracefully, preventing the program from panicking.svd.rsfile for better legibilityTesting
I tested the changes using the tests provided in the
testsdirectory. The changes were validated by running the existing tests to ensure the program behaves as expected and no panics occur.Fixes #1475
