Refactor to enable library use

[leonjza]

While not explicitly mentioned in this projects documentation as a feature (compared to others), the convention to have a static example in the examples directory typically shows how to integrate with a projectdicovery library. However, in the case of this project, the runner lives in an internal directory and will cause go build to fail.

package steampipe-plugin-projectdiscovery
        steampipe-plugin-projectdiscovery/projectdiscovery
        projectdiscovery/table_projectdiscovery_ai_x.go:10:2: use of internal package github.com/projectdiscovery/aix/internal/runner not allowed

Could a small refactor be done to allow integration?
