Some users might want to prefer one babel implementation over another for various reasons. Having to compile the firmware from scratch can be quite tedious in that case. Instead, make the babel implementation switchable at runtime. The implementation can be switched manually using the uci option `babelimpl.impl.impl`, which currently is not upgrade-safe.
