Hi there

We want to share that the latest version (2022.0.0) of pto_merge causes another heap-buffer-overflow bug in the function HuginBase::PTools::setDestImage as well as in the function HuginBase::PanoramaMemento::loadPTScript.

The invalid memory allocation may attribute to the malformed values as parameters to the HuginBase::PTools::setDestImage .

Here is the output of program with address sanitizer attached.

### Envionment
OS: Ubuntu 20.04.5 LTS x86_64
Release: hugin 2022.0.0
Program: pto_merge
To reproduce the problem, we need to build hugin:
sudo cmake -DCMAKE_C_FLAGS="-g" -DCMAKE_CXX_FLAGS="-g" ..

### How to reproduce
$ pto_merge poc-file *.jpg
(*.jpg any name of jpg file including asterisk(*))
poc-file is attached.
