Bug StripeInvoiceItemCreateOptions

[Klynk]

Hello,

I am having trouble with the library, due to what seems to be a bug.

https://stripe.com/docs/api#create_invoiceitem

Here you see 'Amount' is an optional property.

But for your source file, it is not:

https://github.com/stripe/stripe-dotnet/blob/master/src/Stripe.net/Services/InvoiceItems/StripeInvoiceItemCreateOptions.cs

[JsonProperty("amount")] public int Amount { get; set; }

It should be changed to:

[JsonProperty("amount")] public int? Amount { get; set; }

I am having trouble setting UnitAmount because of this, as it throws this exception:
Stripe.StripeException: 'You may only specify one of these parameters: amount, unit_amount.'

OS: Windows 10 (17134.228)
.NET Version: Microsoft.AspNetCore.All (v2.1.2)
Library Version: Stripe.net (v17.10.0)
