Add Java 9+ modules

[jorsol]

There are two distinct modules in this project, the scram-common which contains the SCRAM messages and utilities/functions, and the scram-client module.

Add Java modules using MR-JARs:

• com.ongres.scram.common
• com.ongres.scram.client

@jorsol This is one of the dependencies I need to have a stable module name to resolve pgjdbc/pgjdbc#2657

Let me know if there is any way i can help

Hi @bowbahdoe, there will be a release sooner than later that will be fully modular.

Yet, if you look closely at PgJDBC, this dependency is shaded, so it will not "require" the module-info for the shaded distribution.

Oh that's...well I guess good news but a pain in the ass that tooling is such that I didn't notice.
