    .PARAMETER NetworkId
    The ID of the network for which you want to update the L7 firewall rules.

    A string containing the firewall configuration. The string should be in JSON format and should include the "rules" array, which contains objects with the "policy", "type", and "value" properties.
 
    .EXAMPLE
    $config = [PSCustomObject]@{
        rules = @(
            [PSCustomObject]@{
                policy = "deny"
                type = "host"
                value = "google.com"
            },
            [PSCustomObject]@{
                policy = "deny"
                type = "port"
                value = "23"
            },
            [PSCustomObject]@{
                policy = "deny"
                type = "ipRange"
                value = "10.11.12.00/24"
            },
            [PSCustomObject]@{
                policy = "deny"
                type = "ipRange"
                value = "10.11.12.00/24:5555"
            }
        )
    }
 
    $config = $config | ConvertTo-Json -Compress
    Set-MerakiNetworkApplianceFirewallL7FirewallRules -AuthToken "your-api-token" -NetworkId "your-network-id" -FirewallConfig $config
 
    This example updates the L7 firewall rules for the network with ID "your-network-id", using the specified firewall configuration.
