It seems the Twitchlib.EventSub module doesn't work with the channel.hype_train.begin event

It crashes on the LastContribution object which expects an array of HypeTrainContribution
But it's only a single element

[Error] WebApp.Services.EventSubService: Reason: Application_Error - Message: The JSON value could not be converted to TwitchLib.EventSub.Webhooks.Core.Models.HypeTrain.HypeTrainContribution[]. Path: $.event.last_contribution | LineNumber: 0 | BytePositionInLine: 738.

Problem: Twitch guarantees at least one webhook. If OK responses are sent too late, or in certain situations where Twitch believes you did not get the webhook event, it will resend the webhook. This could lead to duplicate events being processed.

Solution: Create logic for de-duplication of matching msg_id values by reviewing retries in the payload POST from Twitch and/or create a deduplication cache which keeps track of msg_id values.

Additional Scope Enhancements: Custom TTL value for deduplication cache.

I started to work on an application that will use Twitch EventSub, and Twitch provides a handy tool called the twitch-cli to simulate EventSub triggers. However, when twitch-cli creates the necessary headers for EventSub event, it creates them in all lowercase:

This causes failures even within the example application in this repository, notably always triggering a Missing_Header error.

Following the Twitch EventSub docs, they recommend always converting any check to lower case prior to checking the headers.

The UseTwitchLibEventSubWebhooks extension method is currently defined on IApplicationBuilder, which is being phased out in favor of IHostApplicationBuilder.

HostApplicationBuilder is returned by Host.CreateApplicationBuilder() and implements IHostApplicationBuilder.
WebApplicationBuilder is returned by WebApplication.CreateBuilder() and also implements IHostApplicationBuilder.

Can we get support for this new interface?
