`pip install datumaro` does not work without rust installation

[samet-akcay]

Describe the bug

Datumaro cannot be installed without rust. I think this is not ideal. A user should be able to install and use datumaro as a standalone python package. If rust provided additional features, this could be handled properly.

Steps to Reproduce

1. Use a machine where rust is not installed
2. Install datumaro via pip install datumaro
3. Installation will fail complaining that rust is not installed on the system.

Environment:

• OS: Ubuntu 24.04, MacOS
• Datumaro version: 1.10, 1.9.1
• Python version:

I don’t think that Rust will be going away soon. Even if we decided to replace Rust, we would likely end up with Cython which has the same issue. Rust is required for some key dataset importers/exporters like Coco.

I would propose the following course of action:

• Add macos to github action to provide prebuilt binaries for mac
• Add support for Python 2.13 and in the future, be more pro-active about supporting the latest version of Python

That way the vast majority of users will be able to install Datumaro using pre-built binaries without having to compile Rust.
