    .SYNOPSIS
    Update metadata field for an item

    .DESCRIPTION
    Update metadata field for an item

    .EXAMPLE
    $session = New-TssSession -SecretServer https://alpha -Credential $ssCred
    Search-TssMetadata -TssSession -ItemId 5 -ItemType User
    Update-TssMetadataField -TssSession $session -ItemId 5 -ItemType User -ItemDataId 5 -FieldValue 2

    Review output from search command to identify the sequence ID of the metadata field (5 as ItemDataId for this example)
    Update the value to 2
