Add helper function for even more concise API

[webpro]

While the API is fine as it is and the idea is clear from the start that we need separate server and fetch instances, it might still be interesting to look at an even more concise way to instantiate both.

The main idea is to have a single function (or class), let's call it mockFetch in this example:

const [mocker, server] = mockFetch('https://raw.githubusercontent.com');

Multiple servers:

const [mocker, github, assets, gitlab] = mockFetch([
  'https://api.github.com',
  'https://uploads.github.com',
  'https://gitlab.com/api/v4'
]);

The conciseness is more obvious when we want to mock multiple servers, also see here for minimal implementation and larger diff set:

• mockFetch impl
• diff

Alternatively this could be left in userland, perhaps add such an example to Mentoss docs.

WDYT?

Thanks for the suggestion. I'm not a fan of bundling creation of a FetchMocker and MockServers in the same function.

That said, I can see the utility of a more succinct way to create multiple MockServers. Maybe something like this:

const [github, assets, gitlab] = MockServer.createAll([
  'https://api.github.com',
  'https://uploads.github.com',
  'https://gitlab.com/api/v4'
]);

Thoughts?

In that case, I personally don't see MockServer.createAll as an enhancement. You could argue it's more concise, but also there's a level of indirection (frankly, my original idea has the same issue).

You could consider adding something like this idea for userland to the docs for those who might like it:

import { MockServer, FetchMocker } from 'mentoss';

export const mockFetch = baseUrls => {
  const servers = [baseUrls].flat().map(url => new MockServer(url));

  const mocker = new FetchMocker({
    servers
  });

  return [mocker, ...servers];
};

// usage examples:
const [mocker, server] = mockFetch('https://raw.githubusercontent.com');

const [mocker, api, uploads] = mockFetch(['https://api.github.com', 'https://uploads.github.com']);

Might just be a bit less repetitive in certain situations. Personally I like it, but I get it's not Mentoss core API, and in general not everyone will like it.
