.SYNOPSIS
	Pings remote hosts to measure the latency 
.DESCRIPTION
	This PowerShell script measures the ping roundtrip times from the local computer to remote ones (10 Internet servers by default).
.PARAMETER hosts
	Specifies the hosts to ping, seperated by commata (10 Internet servers by default)
.EXAMPLE
	PS> ./ping-remote-hosts.ps1
	✅ Online with 11...40ms latency - 18ms average
