Feature request - configurable interval for logging to services

[Mr-Blinky]

It would be very handy to be able to configure the logging interval for external services such as MQTT and radmon.org, and possibly the others.

I would like the ability to send data to MQTT every 10 seconds and some radmon.org users/stations submit readings at intervals other than 1 minute. The minimum submission interval for radmon.org is 30 seconds as any submissions sooner than 30 seconds are dropped by radmon core.

I'm not sure about the other services (HA, Thingspeak and GMC) as I have no working knowledge of them, and a configurable interval may or may not be useful to them.

I also understand that if just one submission timer is used in ESPGeiger then implementing this would be quite a job.

Cheers
