GeoPackageManager - DocumentFile support

[osedok]

@bosborn Hi Brian, I am starting to look at some changes related to the scoped access to storage (https://www.youtube.com/watch?v=UnJ3amzJM94) and was wondering if it would be possible to provide a method allowing import of the geopackage providing DocumentFile instead of File?

I am thinking of method like getDatabaseAtExternalFile(DocumentFile df) ...

Additional context
The scoped storage will be enforced when the app target SDK is 30+

I will look into options for an overloaded method.

Hi Brian, I was digging the problem in the past week and looks like there is no easy way of getting this supported with the new scoped access to drive on Android without copying the geopackage to app specific folder, which is inefficient and just ridiculous.
I was about to contact Google regarding this and came across this BUg report https://issuetracker.google.com/issues/131356661 - I have added my comment there and your library is mentioned in this thread earlier as well. Hope you will find this useful.

I added DocumentFile support to the GeoPackage Manager.

As you pointed out above, creating or linking an external file currently requires a DocumentFile schema of "file".

Importing a GeoPackage internally will copy the DocumentFile input stream. Exporting a GeoPackage will copy a GeoPackage to the DocumentFile output stream.

Thank you Brian, this looks promising, particularly importGeoPackageAsExternalLink(DocumentFile file ... - I will test at the earliest opportunity and provide my feedback here. Thank you for addressing this.
