Add REST API v0.7 support

[ngfgrant]

Description

In the current state this SDK does not allow users to benefit from the changes in the REST API v0.7.

We have recently run into an issue where we added a PDF via a link. The links MIME type was application/octet-stream which was saved as the MIME type in Uploadcare. The ContentInfo object contains the correct/expected MIME type of application/pdf. However, using this SDK we were unable to access these fields since the SDK uses v0.5 by default and v0.6 if configured.

No open issue around this, but I have just encountered an issue with trying to access file.ContentInfo.

• Adds configuration support for API v0.7
• Sets the defaultAPIVersion to v0.7 from v0.5.

Enables support for new fields added to the REST API since v0.5.

Hi. But what about changes that might break lib behaviour?

E.g.:

• Removed PUT /group/{uuid}/storage/
• Removed DELETE /files/{uuid}/
• Remove the option of sorting the file list by file size from GET /files/
• File information doesn't return image_info and video_info fields anymore in GET /files/{uuid}/
• Removed rekognition_info in favor of appdata in GET /files/{uuid}/
• Parameter add_fields was renamed to include in GET /files/{uuid}/

This change might work for you, but might also be a breaking for somebody else. :-(
