Request to Open Source for Evaluation Binaries

Hello! Thanks for providing this gem to use in our Amplitude integration. It's been really enjoyable to work with so far.

In looking through the gem source, I see that local flag evaluation is handled by precompiled binaries. Specifically:

* [lib/experiment/local/evaluation/lib/linuxArm64/libevaluation_interop.so](https://github.com/amplitude/experiment-ruby-server/blob/bc229a6293e7a978b489a7ed04fb9b1f104b2096/lib/experiment/local/evaluation/lib/linuxArm64/libevaluation_interop.so)
* [lib/experiment/local/evaluation/lib/linuxX64/libevaluation_interop.so](https://github.com/amplitude/experiment-ruby-server/blob/bc229a6293e7a978b489a7ed04fb9b1f104b2096/lib/experiment/local/evaluation/lib/linuxX64/libevaluation_interop.so)
* [lib/experiment/local/evaluation/lib/macosArm64/libevaluation_interop.dylib](https://github.com/amplitude/experiment-ruby-server/blob/bc229a6293e7a978b489a7ed04fb9b1f104b2096/lib/experiment/local/evaluation/lib/macosArm64/libevaluation_interop.dylib)
* [lib/experiment/local/evaluation/lib/macosX64/libevaluation_interop.dylib](https://github.com/amplitude/experiment-ruby-server/blob/bc229a6293e7a978b489a7ed04fb9b1f104b2096/lib/experiment/local/evaluation/lib/macosX64/libevaluation_interop.dylib)

The lack of visibility into what is run in these binaries makes evaluation for security and stability a bit difficult. We use the native mobile clients, such as [amplitude/experiment-ios-client](https://github.com/amplitude/experiment-ios-client), which are open source. I'd like to see if you would be able to provide or (even better) include in this repo the source code for this gem's binary files in the same way.

Thanks very much for the help with this!
