Run a composer update and release an update #24

The AWS SDK version that ships in the released 1.0.0 version is really quite old, and not compatible with Guzzle 7 or up. This can cause version conflicts; usually those are resolved by installing the guzzle7 package which forcefully loads the relevant files to avoid that, however that doesn't work with this package currently.

The error thrown is:

( ! ) Fatal error: Uncaught Error: Undefined class constant 'VERSION' in core/components/awss3mediasource/model/vendor/aws/aws-sdk-php/src/functions.php on line 265

I manually ran composer update in the model folder and that resolved it without further steps.
