Take debugging to a whole new level:
Given a string, remove every *single* bug.
This means you must remove all instances of the word 'bug' from within a given string, *unless* the word is plural ('bugs').
For example, given 'obugobugobuoobugsoo', you should return 'ooobuoobugsoo'.
Another example: given 'obbugugo', you should return 'obugo'.
Note that all characters will be lowercase.
Happy squishing!
