[andyjsmith]

Adds a plugin for viewing information about the native JNI (.so) libraries in APKs, specifically what Java methods they export.

@andyjsmith nice plugin 👍
I released a new plugin list bundle, so your plugin will appear in 'Available' section.

Although, using jadx-gui dependency is a hacky way to get things working. I found these missing APIs:

• access to jadx-gui icons
• show usage dialog

I will create new issues for these in jadx project. Also, feel free to report such missing APIs and I will add them 🙂

Awesome! I wasn't sure how malleable the API spec was. Good to know there might be a better way to use those in the future. If they get added I'll be sure to switch to them and drop the jadx-gui dep.
