Function lal::get_latest_lal_version

pub fn get_latest_lal_version() -> LalResult<LatestLal>

Entry point for lal::upgrade

This mostly duplicates the behaviour in get_storage_as_u32, however, it is parsing the version as a semver::Version struct rather than a u32. This is used regardless of your used backend because we want people to use our main release of lal on CME-release on cisco artifactory at the moment.
