Typing issue with update's optional modelSchema argument

[mabeyj]

Upgrading from 1.5.1 to 2.0.3, I'm getting an error with update calls that omit the modelSchema argument. For example:

import {serializable, update} from "serializr";

class User {
  @serializable
  public name: string = "";
}

const user = new User();
update(user, {name: "Test"});

main.ts:9:1 - error TS2554: Expected 4-5 arguments, but got 2.

9 update(user, {name: "Test"})
  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~

  node_modules/serializr/lib/core/update.d.ts:16:63
    16 export default function update(modelSchema: any, target: any, json: any, callback: any, customArgs?: any): void;
                                                                     ~~~~~~~~~
    An argument for 'json' was not provided.

Seems like these overloads should use export default function instead of export function:

Also, 2.0.3 published on npm differs from 2.0.3 tagged in this repository. The change to make callback optional is included in the 2.0.3 tag, but it's still required in 2.0.3 on npm:

main.ts:9:1 - error TS2554: Expected 4-5 arguments, but got 3.

9 update(User, user, {name: "Test"})
  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

  node_modules/serializr/lib/core/update.d.ts:16:74
    16 export default function update(modelSchema: any, target: any, json: any, callback: any, customArgs?: any): void;
                                                                                ~~~~~~~~~~~~~

Sorry for the late response.

Yeah, there was an issue with the tag. I've set up a postversion script so that hopefully doesn't happen again.

I've fixed the exports (56be5f6226f9d8646c47e8121eea2cba9428cb9d) and published a new version (2.0.5).
