Add YAML-based threshold input options for find_outliers

[d33bs]

Description

This PR adds the ability to receive YAML-based threshold sets as input to be used by find_outliers as part of #4 . I tried to keep this simpler than what is defined in the later comments of the issue, observing YAGNI (we don't yet understand the requirements for different types of thresholds, for example).

Thanks for any feedback you may have!

I am leaving a comment for now as I am curious your responses to my comments. I want to clarify how the function will work if the yaml file is provided. Will it read in one condition at a time and output a df per condition or how will it work?

Please let me know when to re-review!
