v10: Attachments, Read-only shares, and Efficient Sync

v10.0.0 - Squirrel

🐿 Cute, fast, and likes to store things.

This is a major release which introduces attachments, share keypairs, efficient
sync, and much much more. It is the biggest release of Earthstar ever.

As such, this version breaks compatibility with previous versions of Earthstar.

Here are the headline features:

• Attachments. When a new document is written to a Replica you can attach
  arbitary binary data to it. This can be used for sharing large images, music,
  video, anything. There is no size limit.
• Shares with granular read / write access. Share addresses are now the
  public key of a share keypair. The public key grants discovery and read
  access, the secret key grants write access to the replica.
• Efficient sync. Syncing has been completely overhauled to use a new
  efficient reconclition mechanism powered by
  range-reconcile and
  push-pull-push-multicast trees.

The server APIs have also been moved into this repo.

In addition to new features, many APIs have been tweaked or changed entirely.
Please see the API documentation and the README to see what these new API
changes are like.
