[cpackget] Does not seem to install package from requirement of the pdsc

[jkrech]

Describe the bug
When installation the pack NXP::FRDM-MCXN947_BSP@19.1.0-dev16
cpackget should install NXP::MCXN947_DFP@19.0.0 or higher due to a package requirement in the pdsc file.
If NXP::MCXN947_DFP@17.0.0 is already installed the tool's version check is incorrectly seeing the above requirement satisfied.
see: Open-CMSIS-Pack/devtools#1819

To Reproduce
Steps to reproduce the behavior:
Install these packs:
a) NXP::MCXN947_DFP@17.0.0
b) https://github.com/VladimirUmek/NXP_FRDM-MCXN947_BSP/releases/tag/v19.1.0-dev
using cpackget add ... -v

see output:

The last three lines document the bug:
found newer version 17.0.0 is incorrect for the comparison of 17.0.0 >= 19.0.0:_

Expected behavior
The expectation is that no newer version is found an that version 19.0.0 would be installed (latest public version).
