Labels will now be updated if they exists but are a different color. You can use the --skip flag to skip updates.
Here's a usage example and output after changing the color of the "priority 1: urgent" label.
$ node github-label.js 'codenameyau/github-label' -p priority
[-] Skipped label: "priority 3: medium"
[-] Skipped label: "priority 2: high"
[+] Updated label: "priority 1: urgent"
[-] Skipped label: "priority 4: low"
