Popis API PGSONDA.CZ, external API
==================================
API je voláno automaticky, vždy v čase příjmu nových dat ze stanice (1/5/10min interval)
Následuje HTTP/HTTPS volání s parametry, metoda GET
Příklad: https://domena.cz/api.php?name=Sumava&time=1642440896&minspd=1.2&avgspd=5.5&maxspd=10.5&avgdir=325&temp=25.5&hum=50&pres=0&lat=49.9011&lon=14.0611 

name 	=> nazev stanice
time 	=> epoch timestamp 
minspd	=> minimalni rychlost vetru (m/s)
avgspd	=> prumerna rychlost vetru (m/s)
maxspd	=> maximalni rychlost vetru (m/s)
avgdir	=> smer vetru (sever = 0°)
temp	=> teplota vzuchu (°C)
hum	=> vlhkost vzduchu (%RH)
pres	=> tlak vzduchu prepocteny na hladinu more (hPa)
lat	=> GPS Latitude stanice
lon	=> GPS Longitude stanice
