[FEATURE] Implement a Summary table of good and bad dependency counts

[DarthHater]

• What are you trying to do?

Based on user testing, we saw a need for a quick lil table that shows you how many dependencies were scanned and how many are vulnerable

• What feature or behavior is this required for?

This just gives someone a bit more digestable information given we'd like to quiet the output of the tool quite a bit

• How could we solve this issue? (Not knowing is okay!)

It looks like @TheCodinator19 has this more or less working in #28 , so that!

• Anything else?

Have a blast!
