Support package extensions

[rafaqz]

I'm moving a lot of code to extensions and wanted to run JET afterwards. But it seems this is quite difficult?

report_package doesn't report on extensions, and report_file isnt giving me any errors, which is suspicious.

It would be useful to have a function like:

JET.report_extension(Package, :ExtensionName)

You can use Base.get_extension for this:

help?> Base.get_extension
  get_extension(parent::Module, extension::Symbol)


  Return the module for extension of parent or return nothing if the extension is not loaded.

But extension modules dont actually work in report_package.

How do you mean to use that exactly?

Ah I see yeah, my mistake. We'd need to fix the find mechanisms for these.
