Inconsistent way of importing classes in examples

[danielpeintner]

e.g. HTTP

node-wot/packages/binding-http/README.md

Lines 29 to 30 in 7334567

	Servient = require("@node-wot/core").Servient;
	HttpClientFactory = require("@node-wot/binding-http").HttpClientFactory;

vs. CoAP

node-wot/packages/binding-coap/README.md

Lines 29 to 30 in 7334567

	const { Servient, Helpers } = require("@node-wot/core");
	const { CoapClientFactory } = require("@node-wot/binding-coap");

or also in the same file in root README

node-wot/README.md

Lines 144 to 146 in 7334567

	// Required steps to create a servient for creating a thing
	const Servient = require('@node-wot/core').Servient;
	const HttpServer = require('@node-wot/binding-http').HttpServer;

vs.

node-wot/README.md

Lines 182 to 184 in 7334567

	// Required steps to create a servient for a client
	const { Servient, Helpers } = require("@node-wot/core");
	const { HttpClientFactory } = require('@node-wot/binding-http');

I think we should agree on the "proposed" way!

I think I would prefer the

 const { Servient, Helpers } = require("@node-wot/core"); 
 const { HttpClientFactory } = require('@node-wot/binding-http'); 

approach since it looks a bit cleaner and also avoids some redundancy.

Agreeing with @JKRhb direction. Also, this would promote "better" code since with the other approach one can write const BestServer = require('@node-wot/binding-http').HttpServer;
