Rename removeF to removeBy about relude

I'll try to enter some more issues for other things you might be interested in doing, because there are a fair amount of TODOs in the code. Thanks again!

This would just be for ordering? I see there is a showF and SHOW_F. Just want to make sure before I take a stab at updating this.

Oh I see it's being worked on 😄

@arecvlohe - yeah I started working on this one before I saw your comment. Just to explain, for functions like eq in some of our types like List/Array/Result/etc., we have a version of the function that takes an Eq module for the contained type, and a function that takes a simple comparison function (not wrapped in a module). At some point, I think we decided we wanted to prefer the module-based functions, pretending that modular implicits exist, so we used the preferred name eq for the function that takes the module. The function that takes the comparison function was given the name eqF (for equals with a function), but we never liked that name. This effort was to rename eqF to eqBy, but you make a good point that other *F functions should also be renamed to *By. I can take care of this one for now.
