[Feature Request] Support getting HTML as stream

[S-Luiten]

Is your feature request related to a problem? Please describe.
As mentioned in #77, there's a limit of 32kB when getting HTML content, making it impossible to include large strings or images.

Describe the solution you'd like
Same solution as in https://github.com/aspnet/samples/tree/main/samples/aspnetcore/blazor/InputLargeTextArea
This solution uses IJSStreamReference which requires .NET 6.0 or later. To prevent breaking changes, the library can use multiple target frameworks, but then the solution will not be available in the .NET standard 2.0 version.

Describe alternatives you've considered
The 32kB limit can be increased through Microsoft.AspNetCore.SignalR.HubOptions.MaximumReceiveMessageSize, but this is not recommended by Microsoft due to becoming more vulnerable to DoS attacks.

Additional context
I'm willing to make a PR for this.
