sopel-iplookup 1.1.0

Changes

• plugin, config: add config field for MaxMind license key (#4, #5)
  • If no MaxMind key is provided, the plugin will download from a mirror of
    the .mmdb files on GitHub. With a license key, the plugin downloads directly
    from MaxMind.
• plugin: slightly better logging during/after DB downloads
• meta: add automated release workflow using PyPI Trusted Publishing (#7)
