    .SYNOPSIS
    Update Network Site-to-Site VPN
    .DESCRIPTION
    Update the Meraki Network Site to Site VPN Settings.
    .PARAMETER NetworkId
    The ID of the to update
    .PARAMETER VpnSettings
    A Object containing the VPN Settings to apply. This parameter must be used without other parameters.
    .PARAMETER Mode
    The site-to-site VPN mode. Can be one of 'none', 'spoke' or 'hub'
    .PARAMETER Hubs
    The list of VPN hubs, in order of preference. In spoke mode, at least 1 hub is required.
    Hub objects contain the following properties.
    hubId:string (Required) - The network ID of the hub.

    useDefaultRoute:boolean - Only valid in 'spoke' mode. Indicates whether default route traffic should be sent to this hub.
    .PARAMETER Subnets
    The list of subnets and their VPN presence.
    Subnet object contain the following properties:
    localSubnet:string (required) - The CIDR notation subnet used within the VPN
    useVpn: boolean - Indicates the presence of the subnet in the VPN
    .EXAMPLE
    Updating an existing network configured as a spoke.
    # The easiest way to do this is to get the current von settings in an object.
    $VpnSettings = Get-MerakiNetworkApplianceSiteToSiteCpn -id N_1246598574
    # Modify the settings in this object
    # Set the 1st hub destination
    $VpnSettings.hubs[0].hubId = N_5452659857
    $VpnSettings.hubs[0].useDefaultRoute = $false
    # Modify the 2nd hub destination
    $VpnSettings.hubs[0].hubId = N_4585965254
    $VpnSettings.hubs[0].useDefaultRoute = $false
    # Modify the subnet settings if necessary
    $VpnSettings.Subnets[0].localSubnet = 10.5.5.5/24
    $VpnSettings.Subnets[0].useVpn = $true
    # Update the VPN Settings
    Set-MeraqkiNetworkApplianceSiteToSiteVpn -NetworkId N_1246598574 -VpnSettings $VpnSettings
    .EXAMPLE
    In this example we are going to convert a Hub (mess) network to a Spoke network
    In this instance the subnet is already set as we want it so we will only change the mode and add in the remote hub networks.
    
    # Create an array of hubs object
    $Hubs = @(

        localIp: string Local IP address to which traffic will be forwarded
        localPort: string Destination port of the forwarded traffic that will be sent from the MX to the specified host on the LAN. If you simply wish to forward the traffic without translating the port, this should be the same as the Public port

        allowedIps: array[] Remote IP addresses or ranges that are permitted to access the internal resource via this port forwarding rule, or 'any'

    One To One Mapping rules consist of the following schema: * = required
    lanIp*: string The IP address of the server or device that hosts the internal resource that you wish to make available on the WAN
    name: string A descriptive name for the rule
    publicIp: string The IP address that will be used to access the internal resource from the WAN
