Deleting processed files when upload is complete

Deleting processed files when upload is complete

tusdotnet does not automatically delete files after they are processed, it has to be done manually.

When using TusDiskStore, it implements ITusTerminationStore which allows deleting files.

Example usage:

OnFileCompleteAsync = async ctx =>
{
    ITusFile file = ctx.GetFileAsync();
    var stream = await file.GetContentAsync(eventContext.CancellationToken);
    await WriteFileToOtherDisk(stream);

    // Don't forget to dispose the stream if you're using it!
    await stream.DisposeAsync();

    var terminationStore = (ITusTerminationStore)ctx.Store;
    await terminationStore.DeleteFileAsync(file.Id, ctx.CancellationToken);
}
