Use `boost::span` instead of passing `std::vector` by ref

Can we use `boost::span` from Boost.Core instead of `std::vector&` to pass parameters? It shouldn't break API and allows to use other array types such as `std::array`, `boost::static_vector` etc.

Start by locating the public APIs that currently pass std::vector by reference and review how Boost.Core provides boost::span. Check the affected call sites and existing tests, then verify that std::array, boost::static_vector, and other array types can be passed without breaking the API.
