Add support for parsing WH57 (lightning) data for the EcowittClient

[claudobahn]

Note that the wview_extended schema provides support for some of the lightning data, now, and my pull request for adding default unit assignments (weewx/weewx#581) has been merged. I've got a second PR pending for correcting the accumulator's extraction behavior (weewx/weewx#582).

@matthewwall I'm hoping for some guidance from you for pulling in lightning_distance. Basically I'd like to check lightning_time to see if it falls within the current accumulator window and if it does, pull in the distance (which still needs to be converted from km to miles), otherwise discard that value.

Are you aware of how to do that with the existing weewx API?

Hello together, seems like this PR draft was opened more than a year ago.
How's the progress? I just got my own sensor today and couldn't get it working with the interceptor.
I run my WeeWX in a docker (felddy/weewx-docker) and it is working fine for the standard sensors and an additional one.
I figured out the sensor data for the WH57 is not mapped and therefore it can't be passed to WeeWX.
There are many users that have the same issue and probably wait for a solution.
So is it planned to make it working? It seems like this PR could close the gap.
At least the count and distance of lightnings can be send to the WeeWX database.

I managed to get the WH57 work with the interceptor driver

#99 I've have been using it for two months, and it seems to work properly
