TypeError in 'nrfutil pkg generate' - Provide useful feedback

[epac-tom]

Following the Getting started with Nordic's Secure DFU bootloader guide.
When running nrfutil to generate the DFU package using the nrfutil pkg generate command it will bomb out with a TypeError, generated here: https://github.com/NordicSemiconductor/pc-nrfutil/blob/master/nordicsemi/dfu/nrfhex.py#L135
Some searching revealed this post: https://devzone.nordicsemi.com/f/nordic-q-a/48245/typeerror-in-nrfutil-pkg-generate
Indicating the issue with using a project without the correct offset.

Can the code be modified to generate a useful warning message? I'm sure I won't be the last new user to run into this issue, a quick warning would be very useful instead of having to google and eventually find the above post before realising the mistake made.

Hi! We do not have capacity to maintain and release new versions of this utility.
We have made a new utility with the same name and feature set. It can be found here: https://www.nordicsemi.com/Products/Development-tools/nrf-util
