Removes the provided deps from mix.exs
This task also unlocks and cleans any unused dependencies after completion.
Important Note
Igniter does not have a concept of "uninstallers" right now. All that this task does is remove dependencies. If you still have usages of a given dependency, then you will have to clean that up yourself (and likely want to do it before removing the dependency).
Example
mix igniter.remove dep1 dep2
