Untar the archive and then go inside the folder, and you should be able to execute: sudo ./rts_uvc -v 0x0bda -p 0x58f4 --download 170606_6BF129N2_58F4_v7605.rfw

It should say a huge "PASS" and after rebooting the camera should be working.

I haven't been able to try it yet because I don't have my laptop with me.
