Add parser.some()

[mjlescano]

Hi @lancedikson !

What do you think about this? It adds the function Parser.some() to be able to check if the browser satisfies any of the given options.

The function is called some to mimic the native array convention: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/some

This will allow us to change code like this:

const supportsPinch =
  browser.safari
  || browser.chrome
  || browser.opera
  || browser.firefox

for this:

const supportsPinch = browser.some(['safari', 'chrome', 'opera', 'firefox']);

Hey, @mjlescano. Thanks for the PR. I agree it may be useful. Let's add this in the next release 👍

The feature has been published as 2.0.0-alpha.3. I haven't merged this PR since the releasing process is made from develop branch currently, so it's better to apply features to it instead of master.
But, I've cherry-picked your commit and published. So, try 2.0.0-alpha.3 and thanks for your collaboration.

Awesome, thanks!
