Look at Windows registry for Acrobat licensing info

**Why do you need this feature? Please describe.**

On Windows, there are a pair of registry keys that enforce either NGL (next-gen licensing) or serialized licensing. We should add hooks to these keys in the decoder. I'm not sure if it makes sense to add the ability to manipulate these keys, but we should at least check for the presence of these keys in the registry and report their status.

**Describe the solution you'd like**

TBD - I assume for reporting we would include it with the rest of the license reports, but it could make more sense to implement a subcommand or something similar.

**Describe alternatives you've considered**
A clear and concise description of any alternative solutions or features you've considered.

**Additional context**
Add any other context about the feature request here.

The issue names no files, tests, or entry points. Start with the decoder's existing license-report path and determine where Windows registry checks belong; done means reporting the presence and status of the NGL and serialized-licensing keys, while manipulation and a separate subcommand remain design decisions.
