Allows info command to return Previous Evolutions

[XerockXMG]

Description

This PR will make it so that when a user runs the !info command on a mon, it will do a search for previous evolutions along side evolutions (i.e !info Charmeleon would return the data for both Charmander and Charizard). This also introduces a new util file called evoGetData.js. The calcDevolutions part of this can be moved over to the same file that raids uses if required.

Motivation and Context

This was just something that was in #wishlist so I decided to work on adding it
