function Delete-GreenRadiusYubikeyToken {
    <#
        .SYNOPSIS
            Deletes a YubiKey OTP token in GreenRADIUS.
 
        .DESCRIPTION
            Utilizes the GreenRADIUS API to delete a YubiKey OTP token into GreenRADIUS.
 
            Reqires Connect-GreenRadiusApi to have been called at some point earlier in the
            PowerShell session.
 
        .OUTPUTS
            $true if import was successful, $false if not. If not successful, an explanation of the
            failure will also be passed to Write-Error.
 
        .PARAMETER PublicIdentity
            The public ID of the OTP, which presents itself in actual OTP codes as the first twelve
            characters, which do not change.
 
        .PARAMETER Force
            Deletes the token even if the token is currently assigned to a user. If not present, or
            set to $false, then attempting to delete an assigned token will result in a failure
            message.
 
        .PARAMETER RawRequest
            Variable name, without the dollar sign, in which to store the raw request which was
            created and sent to the API. This does not need to be a pre-existing variable. Mostly
            used for debugging this function.
 
        .PARAMETER RawResponse
            Variable name, without the dollar sign, in which to store the raw response from the API.
            This does not need to be a pre-existing variable. Mostly used for debugging this
            function.
