Adding extra query support

[patrioticcow]

idea:

$usersData = $firebase->get('/users', [
'orderBy'      => 'id',
'startAt'      => '1',
'limitToFirst' => '80',
]);

this is good for pagination and other things.

The interface can be modified to add $data to get(). and maybe getString() can be improved

@ktamas77 this one is even better than the previous PR. Any ideas on merging this?

While trying to pass a boolean as value this fails, as it is changed to a string. I have added this code to getString(197):
elseif($val === false) $str .= '&' . $key . '=false'; elseif($val === true) $str .= '&' . $key . '=true';

Hi thanks for applying this must feature. How can I use this with composer instead of the original respiratory ?
I tried:
sudo composer require patrioticcow/firebase-php master
but it gives me error like:

Problem 1
- The requested package patrioticcow/firebase-php could not be found in any
version, there may be a typo in the package name.
Potential causes:

• A typo in the package name
• The package is not available in a stable-enough version according to your mi
  nimum-stability setting
  see https://getcomposer.org/doc/04-schema.md#minimum-stability for more de
  tails.

Could you guide me to the correct solution ?

Extra query parameters can be added from V2.1.0
