Add proper file structure for cogs and extensions

[janine9vn]

Context

Currently, in the singular file that is Lovelace.py, all the cogs and extensions are included in the one file. This cogs should be moved out to separate files and be referenced appropriately.

Details

A potential file structure implementation could look like the following:

lovelace
|
|_ _ _ bot
| |_ _ lovelace.py
|
|_ _ _ exts
| |_ _ IDEA
| | |_ _ _ affinity_group.py
| | |_ _ _ working_group.py
|
|_ _ _ utils
| |_ _ role_checks.py
|
