feat: Updated plugin generator to use SCI types

[eddie-knight]

Part of #90

• Changed from using our custom types to using the SCI types
• Added prettify template function to streamline the underscore/dot fixes
• renamed objects.go -> types.go just for kicks

Some serious nested for loops but makes sense. I could have sworn the dash and underscore replacements were upstream but we still have to do them downstream? Not blocking questions.

@jmeridth We've been doing it here — not sure if we can manage it in the SCI library. There are some cases where we need to clean up the value and other places where we want to keep it the same as it appears in the control catalog.
