[Feature Request]: Convert Estranged.Lfs.Api to utilize minimal APIs instead of controllers

[QuantumToasted]

This may be an overkill suggestion, but as it doesn't seem possible (or easy) to add route prefixes to third-party controllers, I decided to convert them to minimal API methods. This may allow more user flexibility, if for some reason a user may require more configuration beyond customizing the route prefix.
Example for POST /objects/batch:

public static void MapGitHubLfsBatch(this IEndpointRouteBuilder endpoints, string pathBase = "")
{
    endpoints.MapPost($"{pathBase}/objects/batch", async (IObjectManager objectManager, [FromBody] BatchRequest request) =>
    {
        return request.Operation switch
        {
            LfsOperation.Upload => new BatchResponse
            {
                Transfer = request.Transfers.First(),
                Objects = await objectManager.UploadObjects(request.Objects, GenerateTimeoutToken())
                    .ConfigureAwait(false)
            },
            LfsOperation.Download => new BatchResponse
            {
                Transfer = request.Transfers.First(),
                Objects = await objectManager.DownloadObjects(request.Objects, GenerateTimeoutToken())
                    .ConfigureAwait(false)
            },
            _ => throw new Exception("Method not implemented")
        };
    }).AddEndpointFilter<BasicAuthEndpointFilter>();
    
    static CancellationToken GenerateTimeoutToken() => new CancellationTokenSource(TimeSpan.FromSeconds(25)).Token;
}

*Note: BasicAuthEndpointFilter is just a copy of the already existing BasicAuthFilter, converted to implement IEndpointFilter instead of IAsyncActionFilter.

I would be happy to submit a PR, but always like asking in Issues before bothering to do so.

Update: My project which had a problem this proposal was intended to address has fallen out of scope for what I believe the intent of this library was. As such, I have decided to wrap the git-lfs API on my own terms without expecting a third-party library to bow to my will. You are free to still follow up on this as desired, but I do not have any plans to PR or expect a change of this magnitude.

Cheers!
