Ready to be merged (maybe can delete some commented out lines)

Feature or improvement description
This pull request address Issue #119 , where we inadvertently changed nan filtering from an "Any" to an "All" in the conversion of energy ratio from pandas to polars. This pull requests fixes the convention back, and adds a test to confirm the expected behavior (and check going forward)

@paulf81
I've made some updates here based around allowing users to choose whether to use "all" or "any" behavior. In doing so, I decided to move the filtering steps to utilities.

I also made an unrelated to change to have the process of checking inputs to compute_energy_ratio() happen in a separate utility for ease of reading. Feel free to revert that if you disagree.
