bug: Replace object with Extensible

[cre8]

some type are using the object type to extend a type like type DisclosureFrame<T extends object> = Frame<T>;

This could be the reason for some errors we have in the veramo implementation. One of their devs suggested to use an extensible like

interface Extensible {
  [key: string]?: unknown;
}

type DisclosureFrame<T extends Extensible> = Frame<T>;

I don't think it will affect other parts. So Let's give it a try. I think it would be okay to distribute it with the next tag and then check how does it go.

I addressed it in #183

Can we close this issue? @cre8
