Update the Gofile backend to use the new direct upload endpoint based on the latest API changes.
The previous implementation used dynamic server selection, but Gofile has simplified their API
to use a single upload endpoint at https://upload.gofile.io/uploadfile.
This change:
- Removes server selection logic and related code
- Simplifies the Fs struct by removing server-related fields
- Updates the upload process to use the direct upload URL
The upload routine no longer returns a url to download the object.
This fixes the problem by fetching it if necessary when we attempt to
Open the object.
For some reason the parent ID got out of date in the Object (exact
reason not known - but the fact that this was OK before suggests a
change in the provider).
However we know the parent ID as it is in the directory cache, so use
that instead.
