Add rpmmod package type

[mprpic]

RPM modules are a concept in the RHEL/Fedora/CentOS land that allow for grouping of arbitrary RPMs. These modules have their own naming scheme and can be identified using their own purl type. The proposal here is to call that type rpmmod.

More about RPM modules can be found in either of these sources:

• https://docs.centos.org/en-US/8-docs/managing-userspace-components/assembly_introduction-to-modules/

Looking good. Thanks!
Is there a way to find installed modules on a Fedora system?

There is! dnf module list --installed. Alternatively, running just dnf module list will list all available modules and tag them with [d]efault, [e]nabled, [x]disabled, [i]nstalled.
