Retreiving the station id or current conditions
***********************************************

Replace the values "$apiKey" and "$apiSecret" from your account at https://www.weatherlink.com and get the "$stationId"
Execute this code and copy and paste the generated URL in a WEB browser and check out the response

Change "$data" to "current" and set the "$stationId" and get the current weather data
Execute this code and copy and paste the generated URL in a WEB browser and check out the response

Test values from manual https://weatherlink.github.io/v2-api/tutorial
$apiKey = "987654321";
$apiSecret  = "ABC123";
$apiRequestTimestamp = "1558729481";
