Large File Upload

[sanchez]

Need to add some sort of progress handling and indication for when the user uploads a large file. This would include a progress measurement and the number of bytes uploaded/remaining/total. This component should automatically handle chunking the upload and handle the receiving of the file as well. The client-side JS will need to chunk and upload and server-side csharp to handle putting the chunks back together. (This component will purely be aimed at server-side Blazor)
