Create QR Code in PowerShell

<#
.SYNOPSIS
    Creates an in memory (or Base64 encoded) representation of a QR code.

.DESCRIPTION
    A spin-off of the QRCodeGenerator.New-QRCodeText cmdlet, that instead writes the QR code to an array of bytes,
    or as a Base64 encoded string.

    This function clones the API for New-PSOneQRCodeText.ps1, with the exception of -Show and -OutPath:
    https://github.com/TobiasPSP/Modules.QRCodeGenerator/blob/master/QRCodeGenerator/2.6.0/New-PSOneQRCodeText.ps1.

.NOTES
    Requires the [QRCodeGenerator](https://www.powershellgallery.com/packages/QRCodeGenerator/) module.
