feat: handle tuple defaults

[tylersayshi]

I know this does not currently work but hopefully it shows my current misunderstanding and I could get a point in the right direction

For now, I'll just plan to revisit this tomorrow night and see how far I can get

closes #951

I did some work in #1139 please make sure the thing you're trying to make does not exist in the latest rc release
What are you trying to do exactly? I did work with defaults so hopefully can point where you need

[Dimava]

Okay I see this doesn't work, and it's the target of this #951

let t4 = type(["string", ["number", "=", 5]])
console.log(t4(['a',,])+'')

@tylerlaws0n first log the .json value of a type() to see the schema, then search for its properties (.json.sequence.prefix) and what code does work with them
