Build environment map with self-reversed lanes

[MisterioRemo]

Our team have a HD map with self-reversing lanes, so when I try to build an environment, I get an error:

ArgumentNullException: Value cannot be null.

We assumed this is because the self-reversed lanes are only supported on Apollo 5.0. So I temporarily commented out the Apollo 3.0 related code in Build.cs in void PrepareSceneManifest(). Then I managed to build environment successfully.

Сan you add an option to the environments build menu (Build Map & Vehicle) to select which HD map formats should be supported?

Thanks for the detailed report and suggestion; glad you were able to work around it (and thanks for sharing the fix).
