v0.28.2

This release drop support for all the pre-v1 version of meilisearch.

• Fix all the broken things to accommodate the v1 of meilisearch (keys, tasks, dump, etc)
• Provide a new self subcommand that lets you:
  • auto-update mieli
  • generate autocompletion for all the commands so you don't have to remember them
• Add support for the get&delete documents by filter
• When adding documents by path (mieli doc add doc.json instead of piping the file cat doc.json | mieli doc add) mieli will guess the content-type of the file based on its extension.
• Update all dependencies
