fix(sdk): incomplete bundle for web

[markin-io]

Issue being fixed or feature implemented

The fix enables zero-config SDK builds for browser-based apps. This change is needed because configuring webpack at the end-user side became non-trivial, and for certain environments (such as Create React App) it's not possible without ejecting/rewiring configuration which leads to poor developer experience and makes CRA upgrades more complicated.

Issues considered relevant

• js-dash-sdk: yarn build:web can't find package ws #403
• error: Error syncing incoming transactions offset is not uint [RangeError: offset is not uint] #395
• both async and sync fetching of the wasm failed #339
• Error: Assertion failed after funding a new wallet #328
• query using in operator throws Identifier expects Buffer #234

What was done?

• Reworked SDK build command

• Introduced browser entry into package.json to use minified webpack bundle instead of a TS build
  This change makes platform-test-suite to use SDK umd build in karma instead of bundling a TS build, hence providing equal to WebApp conditions

• Exposed DPP primitives and Node.JS essentials via SDK API

• Refactored platform-test-suite to use bundled primitives and essential Platform functions exposed from the dash package

  import { PrivateKey } from '@dashevo/dashcore-lib'
  import { Core } from 'dash'
   
  Core.PrivateKey !== PrivateKey // returns 'true'
  

• Updated relevant tutorials in dashplatform.readme.io to use Buffer from the dash package instead of Buffer from the global scope

import { Essentials: { Buffer } } from 'dash'

How Has This Been Tested?

• CI
• Tested manually by using dash in Create React App
