Add AIS tracker integration

[mib1185]

Proposed change

With this HA can receive AIS messages via udp socket (eq. from an own ais-catcher instance), which enables one to track vessels. Later this integration will be extended to also support fetching ais messages from a server via an tcp connection, which will allow to connect to public AIS instances.

TODO:

• add tests
• add icons to brand repo Add ais_tracker brands brands#5768
• add docs
• (optional) Expose stream close method and make udp-receiver socket optional reusable M0r13n/pyais#148
• limit to device_tracker first

@mib1185 Any reason this is still in draft?

just did not find the time to complete this, yet 🙈 still need to write docs and tbh i'm not really happy with the current implementation of the ais_listener within the coordinator, since it wraps a sync udp socket listener in a async background task 🙁 maybe this is actually ok, but just my gut feeling tells me it's not a good solution 🤔
