Listen for meters continuosly

[KanyonKris]

Currently rtlamr runs repeatedly for a set period of time (ie 15 seconds). Doesn't this risk missing transmissions from meters? Why not run rtlamr continuously?
Before trying your add-on I was running rtlamr via systemd continuously like this:
ExecStart=/bin/sh -c "/usr/local/bin/rtlamr -msgtype=scm,scm+ -format=json -filterid=56147164,95099776 -unique=true | /usr/bin/jq --unbuffered -c '. |= del(.Message) + .Message' | /usr/local/bin/stdout_httpd -port 8164"
