Rust API

[astrauc]

Callable rust API. Includes small changes to the CMakeLists.txt files in root, src folder, api/cpp folder, and keyvalue_parser folder.

Changes to cmake mainly add another option for building, such as build for static linking and building only the libraries. Changes to keyvalue_parser modify where it writes files to (changed to modify to the build tree instead of the source tree)

Thanks @astrauc, looks good so far. A couple quick requests if you have time:

• Can you put together some notes on building this for Rust that we could add to https://github.com/aphysci/gravity/wiki/GravitySetup?
• Can you write some text for the 2 examples that we could add to https://github.com/aphysci/gravity/wiki/GravityExamples? If you want, you could do this in your own wiki space so that you can play with the formatting a bit, and then we could move it over.

Missed this file at first glance - this covers the setup notes I asked for.

I have the text for the examples already ready as well, just have to move them over!

I can also move the notes for the setup into the wiki for simplicity

It would be good to mention someplace that we have a dependency on at least cargo version 1.85 (edition 2024) - or am I missing something? apt install on Ubuntu 24.04 installs 1.75.0, so would be good to give a heads up. And some environments make installing with https://sh.rustup.rs challenging....

After deleting my Cargo.toml file, I was able to get the latest and now the tests and examples work for me even if spdlog is installed locally. Thanks @astrauc!

The windows build for this fork is failing because https://cytranet.dl.sourceforge.net/ (where some windows dependencies live) seems to be offline. I don't think it has anything to do with the changes here. Will kick off the build again later when that site is hopefully back online.
