Using F# Record types as named parameters

[TheAngryByrd]

As of now, you can't use named parameter queries easily from F# because the parameter handler looks for anonymous objects which F# doesn't support.

The code for detecting anonymous types just looks to see if the object has a namespace. You can do this from F# by declaring types in a module only file like

module Parameters

type ByName = {
    name : string
}

but this is not obvious nor optimal.

I have an Stackoverflow question about detecting F# record types from C# at runtime to see if we can maybe add a detection to Marten main. If that's not easy/possible we should consider alternatives.

I did a bit of research and this will work with the existing code (https://github.com/JasperFx/marten/blob/b752e79d473783651a763b18c2dc0f8c52d95816/src/Marten/Util/CommandExtensions.cs#L63) if we can just PR an extension to the detection code. Just have to do it via attribute inspection so as to not introduce the link to FSharp.Core
