Compile apps/seastack/single_run.cpp with chrono v10

[hfchen20]

Hello @dav-og ,

Many thanks for great efforts on this package!

I git-cloned and compiled on WSL Ubuntu chrono's main branch last week. Now I'm trying to compile sea-stack. The following error appears due to a refactoring of chrono_parsers API (see this commit). m_script_directory seems to be replaced with
ChYamlFileHandler m_file_handler
Is there a quick fix for this?

Thanks,
Haifei
