Set Licence type expression & repo url on package info

[thompson-tomo]

Summary

I wish for the nuget packages to have the licence expression property set correctly and the repository url

Details

The licence expression property should be set to the correct licence type (depending on the repo) as this will enable analysis of licences in use to occur in external tools & the license type will be shown in Nuget etc. By providing the repo url it will make it easier to contribute and can be used by source-link.
