Fixed beacon timeout handling.

[raufaser]

I am using the time library and convert the gps time to unix timestamp. Now it is possible to use beacon timeout of any number of minutes. E.g. 300 = 5 hours.

thanks for the pull request, i never got it perfectly running. I did some updates on mainline as there was a lot of maintenance missing in the last time.
Can you update your pull request with the last changes? - otherwise I can also add your changes, but than your name will not appear here which would be a pity

tbh I have no idea how to do that. In theory it is absolutely clear to me what to do. I have to merge your new commits with my commit. I guess I have to learn a lot about git and how to use it in Visual Studio Code. A lot of the teminology is still unclear to me. But I am willing to learn :)

if you have access to a console try this commands:

git remote add upstream https://github.com/lora-aprs/LoRa_APRS_Tracker.git
git fetch upstream
git rebase upstream/master

there is a high possibility that you will get merge conflicts, you can solve them very easy with visual studio code.
make a new commit and push it.

there is a high possibility that you have to force the push:

git push -f origin master

Well. I gave my very best :) Thanks for the explanation.
