this PR makes the following changes to update the underlying license model to have more expressive capabilities it also provides some guarantee's surrounding the license values themselves - Licenses are updated from string -> pkg.LicenseSet which contain pkg.License with the following fields: - original `Value` read by syft - If it's possible to construct licenses will always have a valid SPDX expression for downstream consumption - the above is run against a generated list of SPDX license ID to try and find the correct ID - SPDX concluded vs declared is added to the new struct - URL source for license is added to the new struct - Location source is added to the new struct to show where the expression was pulled from
