Use Nix for building the project

[Archisman-Mridha]

I'm currently building the project on my Mac by running sh ./scripts/mac_os_build_setup.sh. It's installing a bunch of tools using Homebrew.

It'll be really useful - if you guys keep an option - to build the project using Nix.

If agreed, then let me know. I can do a little contribution :).

Sounds good! I have no experience with Nix but I'd always love to support more host build systems.

Would definitely appreciate your contribution!
