Create minimal examples for a few programming languages

[gsmachado]

Based on the following tutorial:
https://github.com/vladimirvivien/go-cshared-examples

Create examples (maybe in a different repo, like AxLabs/neofs-shared-lib-examples or something like that) for the following programming languages:

• Python
• Node
• Rust
• C#

The goal here is to show how to load our shared library and perform crucial operations (i.e., create a file, get a file, delete a file).

The goal IS NOT to create wrappers for each programming language. Just to show viability and how to do it. 😄
