Add parser for `std::map<std::string, std::pair<int, int>>` properties
Currently, there is only an implementation for properties of type std::map<std::string, std::pair<double, double>>
. For the development of TimepixTelescope/Kepler I would like to use a property of type std::map<std::string, std::pair<int, int>>
.
I tried implementing the parser in this MR. Please let me know if there are any issues with my request.
