Adds and configures eslint-plugin-import.
Maintains import-sort rules which are auto-fixable.

Is this doing what you want? e.g. it turns the imports in bitcore-node/src/config.ts from

import { cpus, homedir } from 'os';
import { ConfigType } from './types/Config';
import { merge } from './utils';
import parseArgv from './utils/parseArgv';

to

import { cpus, homedir } from 'os';

import { ConfigType } from './types/Config';
import { merge } from './utils';
import parseArgv from './utils/parseArgv';

Perhaps you meant the import/newline-after-import rule?
