fix!: Switch interface to consistent snake_case naming

[contagon]

There was a handful of the API that had left over camelCase usage. Switch them all to snake_case.

[Copilot]

Pull Request Overview

This PR refactors the codebase to standardize naming conventions by converting camelCase method names to snake_case format, improving consistency with Python naming conventions and making the API more idiomatic.

• Renamed methods in SO3 and SE3 classes (e.g., fromMat → from_mat, toMat → to_mat, toEigen → to_eigen)
• Updated string conversion methods (e.g., toString → to_string, toStringBrief → to_string_brief)
• Refactored C++ binding functions to use snake_case (e.g., makeTypes → make_types, makePipelines → make_pipelines)
