ProjectPackages should allow subpackages

[levinalex]

right now ProjectPackages uses filepath.Match to check which parts of the stacktrace to filter:

bugsnag.Configure(bugsnag.Configuration{
    ProjectPackages: []string{"main", "example.com/foo/*"},
}

However, wildcards (because of Filepath.match) will only be expanded into a single 'directory'. This matches example.com/foo/bar and example.com/foo/baz but not example.com/foo/bar/fred or example.com/foo/bar/fred/bar.

(my workaround to that was to say {"example.com/foo/*", example.com/foo/*/*", example.com/foo/*/*/*"} but that is brittle and ugly)

It would be nice if it was possible to match all subpackages explicitly (maybe via "example.com/foo/**"?)

I'd take a stab at implementing this if you are open to it

Hey @levinalex - this seems like it would be a solid addition to the library. If you want to take a stab at it that would be great. If not then someone will get around to this soon!
