Catalog v1

[cryptoquick]

Catalog v1 Files need a new header format which must contain an unbounded amount of metadata in CBOR format, preceded by its length. Then, every segment hash will be appended to the file in order.

Files will end in .cat, and the metadata section needs to support properties specific to each frontend. It will also need to be able to include other filesystem metadata, such as file name and dates. All this data will be optional.

Data should include file MIME type and creation date.

An endpoint should be available to return the raw catalog file, in addition to a parsed version as JSON.
