More Updates to ButterCMS

[bjimzTechtonic]

ButterCMS uses Filestack for their Image API https://buttercms.com/docs/api/?javascript#image-api https://www.filestack.com/docs/api/processing/

Does have support for WebP / Optimized Image Encoding:

There are a ton of other image features, but:

• No focalpoint support that I could find
• No facedetection support that I could find

Other things:

• Couldn't determine if their media API supports assets fingerprinting
• Updating content relations field to match field format of the other CMSes
