fusclient: fix 403 Client Error: Forbidden for recent devices

On at least SM-S908B we get the following error trying to download a FW file:

$ samloader -m SM-S908B -r BTB download -v S908BXXS6CWH6/S908BOXM6CWH5/S908BXXU6CWH5/S908BXXS6CWH6 -O .

Fix by changing download url. Patch has been adapted from https://github.com/ananjaser1211/SamloaderKotlin/commit/8a0d50428ac7080f9c2cbe8847da06bbccb20798.

It should be cloud-neofussvr.samsungmobile.com, not cloud-neofussvr.sslcs.samsungmobile.com (which doesn't exist)

Indeed, thanks for spotting that!

Can confirm that this fixes downloading the latest firmware for SM-A705FN too.

Sorry I didn't notice this -- for some reason despite being a repo in my profile I wasn't set to watch... that's fixed now.

I've confirmed the problem exists and this fixes it for my device as well, merging! Thanks everyone!
