This orb doesn't allow using the parameter --parallel to build multiple lambdas at the same time

Hey @rsorelli-hedgepoint!

Thanks for opening this issue. I am working adding a build_arguments parameter to the sam/build command and sam/deployjob that will enable you to add additional flags to thesam buildcommand like--parallel`.

We'll be looking to cut a new major release soon, which will include this feature.

Thank you!

Best, Brian
