Create factories for Handlers, Actions, Validators, and Types

[juni-b-queer]

It would be really helpful for test writing and even use in code to have factory methods on all of the major classes and types that are frequently used.

Low complexity idea

Add a static make to handlers, actions, and validators Instead of new CreateSkeetHandler(args) it would be CreateSkeetHandler.make(args) It doesn't change a lot, and both ways would still work, but to me it feels cleaner, and would be easy to for making mocks in tests.

For types, it would be similar, and I'd have to create a factory for each type, but most of the parameters are null able and could be auto filled CreateSkeetMessageFactory.make(args) It'd have args for each attribute.

More complex idea

Specifically for Types, this could cut down test size by probably 50% In addition to the make method, For jetstream messages, it could have chaining methods that allow for adding optional parameters. JetstreamMessage.make().isCreate().isLike().fromDid(did).toDid(did) so on and so forth. This would be similar for subjects, replies, records, and any other types.

I also want to add these chaining methods to Validators so I could do InputEqualsValidator.make("input").not() to negate the validation.

Thought for the type factories

Classes of the same name, and change types to interfaces(maybe?), for example

class JetstreamMessage implements JetstreamMessageInterface extends [name for an abstract type class] {

   // class variables, matches interface

   constructor(args){
      //set values
   }

   static factory(): JetstreamMessageFactory {
      return new JetstreamMessageFactory()
   }

   static find({searchArgs}): JetstreamMessage {
      // api calls to find the given record and return it as JetstreamMessage
   }

   // getters/setters for variables
}

class JetstreamMessageFactory implements JetstreamMessageInterface extends AbstractMessageFactory {

   did(messageDid: string): JetstreamMessageFactory {
      this.did = messageDid;
      return this;
   }

   // other methods for properties

   create(): JetstreamMessage {
      // convert back to JetstreamMessage
   }
}

I'll be doing a combination of both the simple and complex idea. I've already completed Handlers, Actions, and Validators. in #44 and #45
