Fix deprecated PackageLicenseUrl and update Microsoft.Bcl.AsyncInterfaces

- Replace deprecated PackageLicenseUrl with PackageLicenseExpression (Apache-2.0)
  Addresses #168: the old URL format is deprecated by NuGet and caused a 404
- Update Microsoft.Bcl.AsyncInterfaces from 5.0 to 10.0.3
  Eliminates NU1605 package downgrade warning: System.Threading.Channels (*)
  transitively requires 10.0.3, but the explicit 5.0.0 requirement caused it
  to be downgraded at resolution time
