Measure-RvoObfuscation should have a 'SignerThumbprint' option for whitelisting

[LeeHolmes]

Example implementation:

ipmo 'C:\Program Files (x86)\Entity Framework Tools\NuGet Packages\EntityFramework.5.0.0\tools\EntityFramework.psm1'


$a = Get-WinEvent -LogName Microsoft-Windows-PowerShell/Operational | ? ID -eq 4104
$b = $a | Get-RvoScriptBlock
$content = [System.Text.Encoding]::Unicode.GetBytes($b[0].ScriptBlock)
$c = Get-AuthenticodeSignature -Content $content -SourcePathOrExtension ".psm1"
$c.SignerCertificate.Thumbprint -in @("19F8F76F4655074509769C20349FFAECCECD217D")
