License Key Validation

[ngschaider]

Hello,

I experienced an issue where my license key was not accepted by nfpm.

My license key was:
cfxk_bJ1pvLDI2d3rISsoG8E3_qC1vJ

I triple-checked if I copied everything the right way. As you can see, there are license keys with only 31 characters.
This check propably caused the issue:

nfpm/src/Modules/Setup.cs

Line 116 in 55589be

if (Regex.IsMatch(s, @"[\d\w]{32}")) return true;
