Create a morphir-jvm CLI

[DamianReeves]

The CLI should insulate users from having to deal with npm and should provide a pathway to make it easy to integrate with tooling that JVM/Scala users will be used to.

The CLI will follow the git style of having commands and sub-commands.

CLI Commands will include:

• build executing "targets" for reading, emitting/"making", code-gen, etc - this command will result in a model with its generated sources being available
• workspace init - initialize a morphir workspace
• workspace info - get information about a morphir workspace

More TBD
