Generated code doesn't work with LicenseToCIL 1.0.0

Following the tutorial in a .net 4.7.2 console app with FSharp.Core 4.5, the generated code produces an exception

System.TypeInitializationException
  HResult=0x80131534
  Message=The type initializer for 'Rezoom.SQL.Mapping.CodeGeneration.ReaderTemplate`1' threw an exception.
  Source=Rezoom.SQL.Mapping
  StackTrace:

   at Program.MyModel.Migrate(MigrationConfig config)

Inner Exception 1:
MissingMethodException: Method not found: 'Microsoft.FSharp.Core.FSharpFunc`2<S`1<!!0>,Microsoft.FSharp.Core.FSharpFunc`2<LicenseToCIL.IL,S`1<S`1<!!1>>>> LicenseToCIL.Ops.newobj'x(System.Reflection.ConstructorInfo)'.

It seems to be a problem with the LicenseToCIL dependency, because pinning at 0.3.0 fixes it.

Same underlying issue as #37.
