Add APRS device tracker component

[PhilRW]

Description:

This new APRS component keeps open a connection to the APRS-IS infrastructure so messages generated by filtered callsigns can be immediately acted upon. Any messages with certain values for the 'format' key are position reports and are parsed into device tracker entities.

Pull request in home-assistant.io with documentation (if applicable): home-assistant/home-assistant.io#9056

Example entry for configuration.yaml (if applicable):

device_tracker:
  - platform: aprs
    callsigns:
      - 'XX0FOO*'
      - 'YY0BAR-1'

Checklist:

• The code change is tested and works locally.
• Local tests pass with tox. Your PR cannot be merged unless tests pass
• There is no commented out code in this PR.

If user exposed functionality or configuration variables are added/changed:

• Documentation added/updated in home-assistant.io

If the code communicates with devices, web services, or third-party tools:

• New dependencies have been added to the REQUIREMENTS variable (example).
• New dependencies are only imported inside functions that use them (example).
• New or updated dependencies have been added to requirements_all.txt by running script/gen_requirements_all.py.

Yeay! First(?) hamradio component for HA! :-)

I'm trying to figure out how to pass the PlatformNotReady back to the main thread.

I don't quite get what's going on here with codecov. I've rebased onto the latest dev branch but it says I've changed all these files that I haven't touched in my commit(s).

I just wanted to drop by and add some support for this component. I was just thinking about APRS and telemetry and thought "wouldn't it be cool for Home Assistant to be able to receive and transmit telemetry on the APRS-IS network!?" Sure enough, I come to find that the community is already working on this! Thanks! @PhilRW!

[PhilRW]

Long-term we could send locations and messages to the network, but I'm starting simple with a device tracker component.

[PhilRW]

Perhaps some additional developer documentation is needed when adding a codeowner.

[PhilRW]

@syssi Now that I finally have it passing CI, could you take another look? 🙂

[balloob]

Ok to merge when tests converted from class functions to standalone functions and PlatformNotReady replaced with error logging.

[PhilRW]

Fixed.
