New module: Enumerate targets android apps

[domwhewell-sage]

This PR will search the google play store for official android applications created by the target organization

1. It searches the google playstore with the ORG_STUB or will consume android CODE_REPOSITORY events and re-emit them as MOBILE_APP
2. Requests the details page for each app listed, in the "App Support" section the publisher lists details about themselves, if the Website / Support Email / Privacy Policy fields contain in-scope urls then the App is deemed in scope
3. The module then raises a new event type MOBILE_APP which will be consumed by other download modules

FYI:

• I have removed the URL validation for now, as the app_id is passed to the playstore as a query parameter which the validator will not accept 😟
• I am marking this pull request as ready for review now I will update the steps to get a mobile looting set of modules in Discussion Mobile App Looting / Analysis #1219

Nice work on this. Mobile apps are a huge attack surface so this is really exciting.

One thing though is that it looks like BeautifulSoup is taking up an enormous amount of CPU. In some cases it is blocking the event loop for 5+ seconds. Whenever possible we should avoid parsing HTML and use the async regex helpers instead, or the yara helpers like in postman_download.

Once the performance stuf is fixed this should be good to merge.
