sort firmware version by autoupdater/opkg specification

[Djfe]

Expected Behavior

Firmware-Version is sorted newest to oldest

Current Behavior

sort order: numbers come before letters when they should come afterwards
2019 is displayed before v2019 even though v2019 is classified as newer by the autoupdater (same goes for v2023.2 for example)

root@ffac-test-7360v2:~# opkg compare-versions "2019" '>>' "v2019"
root@ffac-test-7360v2:~# echo $?
1
root@ffac-test-7360v2:~# opkg compare-versions "2019" '>>' "2018"
root@ffac-test-7360v2:~# echo $?
0
root@ffac-test-7360v2:~# opkg compare-versions "2019" '>>' "2023"
root@ffac-test-7360v2:~# echo $?
1

I just ran across another case:
someone build their own firmware and gave it GLUON_RELEASE v2023.2.x. Both opkg as well as meshviewer classify this as newer than v2023.2.1-1

root@ffac-test-7360v2:~# opkg compare-versions "v2023.2.1-1" '>>' "v2023.2.x"
root@ffac-test-7360v2:~# echo $?
1
``

So there are actually cases where the current code sorts correctly. I guess, it depends on where the letter is?
A letter at the beginning of a version number is considered older by meshviewer. While its considered newer when its in the middle.
