Create API blueprint spec

[apast]

Provide 2 http endpoints that accepts JSON base64 encoded binary data on both endpoints:

<host>/v1/diff/<ID>/left <host>/v1/diff/<ID>/right

The provided data needs to be diff-ed and the results shall be available on a third end point

<host>/v1/diff/<ID>

The results shall provide the following info in JSON format

• If equal return that
• If not of equal size just return that
• If of same size provide insight in where the diffs are, actual diffs are not needed.
  • So mainly offsets + length in the data

It should be updated for new report format with statuses
