Update Rclone to v1.73.0 for Drime Cloud Storage support

[chnirmal]

Pre-Submission checklist
[x] There is no existing issue that already asks for this feature.
[x] The feature already exists in rclone (on your PC or in Termux)
[x] I am prepared to help make this feature (by testing)

What version of Round Sync are you using?
Version: v2.5.6.

What problem are you trying to solve?
I am trying to use Drime Cloud Storage with Round-Sync on my Android device. I have already successfully set up Drime on my Mac using the latest rclone v1.73.0.

However, when I try to import the .config file into Round-Sync, it fails because the app is currently running rclone v1.71.0, which does not yet support the Drime backend. This prevents me from syncing my Drime files on mobile.

What should Round Sync be able to do differently to help with this problem?
Round-Sync should update its internal rclone binary/library to v1.73.0 (released Jan 30, 2026).

This update would provide native support for Drime and other recent rclone improvements. Once the binary is updated and the app is rebuilt, users should be able to import or create Drime remotes directly within the app.

+1 but for "Filen" support.

I built the APK using (OpenAI) Codex and published it in my fork. I didn’t make any changes to the code.

+1 for this. Much needed for new remotes support (Internxt)

I messed around a bit with AI to make a flexible build environment for this, so you can easily change/upgrade rclone, without having to figure out how to build something and install 300 tools just for this. It all runs in a single docker container that is removed afterwards.

I used it personally to have Kdrive support, that is currently not merged yet (the "tofee" reference in the make file). There's built in support for the latest rclone directly.
