@clean_names has a little problem with abbreviation feature name

[math4mad]

If feature is abbr. then will add _, like id => i_d, bmi=>b_m_i

For the @clean_names() macro, we actually wrap the polish_names() function from the Cleaner.jl package.

I would suggest opening an issue there: https://github.com/TheRoniOne/Cleaner.jl

You're right that when janitor sees multiple consecutive capital letters, it doesn't add underscores to separate them.

I'll leave this issue open on our end so we can track this. Thank you!

This is now fixed thanks to a fix to Cleaner.jl (Thanks @TheRoniOne!)
