Expose http response content headers via Box SDK

[Yosif-Smint]

Is your feature request related to a problem? Please describe.

The problem that I am facing is that BoxFilesManager does not provide an API for getting System.IO.Stream related information.
It does not expose 'content-type', 'content-length' nor 'content-disposition' content request headers.

Why am I requesting this?
Box API does not return any whatsoever mime-types.
I don't want to guess the mime-type or parse it on the fly based on the file extension of a BoxFile.
Working with generic mime types could introduce security issues.
I would prefer If I can return the correct mime type to the front-end, so that the browsers knows how to handle it correctly.

Would be happy to hear from you or answer questions.
Thanks!

Describe the solution you'd like

See Box.V2.IBoxResponse

public interface IBoxResponse<T> where T : class
{
    ...

    HttpResponseHeaders Headers { get; set; }

    /// <summary>
    /// This could be added
    /// </summary>
    HttpContentHeaders ContentHeaders { get; set; }
}

See Box.V2.Request.HttpRequestHandler line 204 on the main branch

var boxResponse = new BoxResponse<T>
{
    Headers = response.Headers,
    ContentHeaders = response.Content.Headers, 

    // Translate the status codes that interest us 
    StatusCode = response.StatusCode
};

Afterwards we can introduce a new set of BoxFilesManager methods that can return the response itself IBoxResponse<> or we can create a custom return type. No preference about that.
E.g.

Task<IBoxResponse<Stream>> DownloadStreamAsync(string id, string ...)
