[question] bindings for C# and .net

Issue description

Both the product page and the README of this repository have no mentions of bindings for C# and .NET platforms such as:

1. Themis integration with ASP.NET Web API
2. Themis integration for mobile apps in C# (Xamarin)

Seems like Microsoft ecosystem gets little love from the themis team which is unfortunate for devs engaged in that ecosystem.

Are such integrations even on your roadmap? If not, it would be nice to have this fact documented in your readme and in the product page (or in the FAQ section at least).

Thanks in advance for the reply.
You are awesome.

TL;DR: If you need one earlier than we build one - feel free to build your own, we’re happy to help!

(Long boring manager answer ahead)

Themis feature changes are driven by two main drivers:

• our own internal needs - Themis is baseline component in all our products. In this regard - as soon as any of our tools require C#/NET API (that’s typically customer-driven), there will be a C# API. This general vector has been outlined in docs in couple of places, I believe.
• open source contributions - anyone is welcome to build/improve wrappers, we are happy to help do that properly.

In fact, MS ecosystem has some love already - Themis builds on Windows well (I suspect all infra for that will surface in upcoming releases), one of our customers uses it, but via NodeJS + Electron bindings, but this might not be very helpful if you want C# one.

@dodikk thank you for the question! do you have some specific needs for Themis on C#?

That's a mobile app built with xamarin which obviously needs some security improvements.
The back end might migrate to ASP.NET web API some day, so server side .NET has a lower priority so far (for my case).

FYI: Here is a proof of concept for xamarin which adds themis as binding projects.

P.S. An example for cross-platform code (Xamarin.Forms or .NET Standard) will follow soon in that repo. And some slightly more beautiful interfaces too.
P.P.S. No plans for maintaining a nuget package yet.

wow, that's something very special. Thank you, @dodikk! We'll take a look

Done for a subset of TSCellSeal / SecureCell API.

@vixentael here is another demo for the .net MAUI toolchain.

I hope it might be used as a step towards your C#/.net related guides and docs some day.

P.S. Around 2024 microsoft is going to deprecate xamarin so MAUI will be their main mobile framework.
