Fix #45 and making it possible to only import the parse method

[Jikstra]

As it's possible to partially import the parse method from errorStackParser, the this invokation will be wrong as currently the parent object is not explicetly bound to the parse method (and all other methods). So something like this fails:

import { parse } from 'error-stack-parser'
...

const frames = errorStackParser.parse(error);

with following error: TypeError: Cannot read property 'parseV8OrIE' of undefined

Description

I created an errorStackParser object, added .bind(errorStackParser) to all methods and returned this obj.

Motivation and Context

See description

#45

• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to change)

Checklist:

• node_modules/.bin/jscs -c .jscsrc error-stack-parser.js passes without errors
  • jscs isnt working for me, but also not in the dependencies? Is this still up to date?
• npm test passes without errors
• I have read the contribution guidelines
  • this file doesnt exist or i didnt find it
• I have updated the documentation accordingly
  • nothing changed
• I have added tests to cover my changes
  • i could add a simple test, but it needs to run in another sandbox as the browser sandbox doesnt have access to require/import

If this is still an issue, can you resolve the conflict and ping me back once done?

I have merged and made changes in 1588ff9#diff-4cca18169d8ca3240eb941bdc4b36cfc0c492cbfdca198862f85db32c986c468 to prevent partial import.

Please use this way starting with version 2.1.0 which I just published:

const ErrorStackParser = require('error-stack-parser');
// other code
const frames = ErrorStackParser.parse(err);
