Added support for additional thumbor filters: animated, autojpg, format, proportion, sharpen, smartCrop, and stretch which bring also bring support for the auto crop feature to the thumbor-like URLs.
Also added support for image requests using query parameters instead of thumbor-like URLs. Those can be enabled in the config object of the ImageHandlerContext by setting the useQueryParams option to true (default to false).
Beside the new features, some improvements have been made to the package. These include better user-input validation and normalization before using the input in image requests.
