PowerShell 7 / Windows 11 Support

[ivassallo19]

Haven't seen a mention of this anywhere. Would be great for AaronLocker to be updated, to support PowerShell 7 / Windows 11. Currently, there are a couple of points.

• The .ps1 files look for PSVersion 5.1. The way it looks for it (Major -ne 5 -or Minor -ne 1) means that if 7.1 exists it will pass, so that should be improved anyway
• SupportFunctions.ps1 uses 'Get-Content -Encoding Byte', and Byte encoding type was removed/replaced, so this causes an error

I've been able to modify my copy, but would be useful to have the main branch updated with these changes.
