Missing support for ddcutil 2.0.0 (1.4.1 works)

[JamiKettunen]

With ddcutil v2.0.0 when I run the following:

env NO_CONFIG=1 fastfetch --load-config all --show-errors --stat --multithreading false --disable-linewrap false --hide-cursor false

I only get Brightness: No result is detected. while installing ddcutil v1.4.1 makes Brightness (HPN): 89% and Brightness (VSC): 60% appear as expected.

Fwiw I was testing this on Chimera Linux with my packaging looking like chimera-linux/cports@master...JamiKettunen:cports:fastfetch

Let me know if you need any other details or if this is reproducible under another distribution with an updated ddcutil version :)

Please make sure that ddcutil getvcp 10 works first, and try fastfetch again.

If it still doesn't work, there must be some imcompatibility between 1.4 and 2.0. The code is very simple and you may debug it. If you can't, I'll try debug it myself after Fedora upgrades ddcutil to 2.0.

[JamiKettunen]

Sorry for the long delay, that seems to have done the trick. I suppose it should try both sonames since for fastfetch purposes both seem to be "compatible"? I suppose it'll crash when that's not the case but could be somehow dealt with as well if it comes up

FF_LIBRARY_LOAD will try lower versions if the specified version is not found.

Looks like it broke again in e9c2a43:

From ddcutil release notes:

With the ability to configure libddcutil operation both by the ddcutil
configuration file and by passing an option string in the ddca_init() arguments,
several API functions are no longer needed and have been removed:

[...]

• ddca_set_default_sleep_multiplier(), ddca_set_global_sleep_multiplier()
