Fix for PHP 7 compatibility

[skeyby]

We recently updated our machines to PHP 7.1 and the code got stuck in the fgets because it was failing to understand that the transfer was chunked.

We did a side by side trace with PHP 5.6 and found this line to behave differently.

Now it's working ok.

Hi, i had a similar issue on php7 and on the file: sagCurlHTTPAdaptater.php,
fixed on line 124, by replacing
$response->headers->$line[0] = ltrim($line[1]);
by
$response->headers->{$line[0]} = ltrim($line[1]);

Ok, I forked your project, and indeed your change is mandatory on PHP 7.x.
So I consider your repo as master - is more up to date.
