    Set FreeBSD workflow timeout

commit ff1f51c
Author: Steffen Winter <steffen.winter@proton.me>
Date:   Wed Oct 18 22:26:36 2023 +0200

    Set FreeBSD workflow timeout

    Recently the FreeBSD workflow has started to hang in a boot loop when
    the VM starts up. The issue is being tracked upstream but there is not
    response at the moment.

    To work around this set a timeout to not waste CI minutes. Other
    workflows might also want this change since they don't take 20 minutes
    anyway.

    Fix short conversion of 1000-1023 *iB

commit f798acd
Author: scorpion-26 <dev.scorpion26@gmail.com>
Date:   Tue Sep 5 18:00:47 2023 +0200

    Fix short conversion of 1000-1023*iB

    floating_humanizer([1000-1024], true) with base 8 returns "2K", whereas it should return
    "1.0K" to align with other formats. The conversion is also broken for
    all other units(e.g. 1023M is also broken and returns "2G")
