Rename package to geo-utils-cpp (repology name conflict)

[gistrec]

The name geo-utils on repology already refers to another component, so the distribution package name had to change. Renames cover pkg-config, CPack, CMake find_package (GeoUtilsCpp) and the GEO_UTILS_CPP_* option prefix. The public C++ API — target geo::utils, namespace geo::, headers <geo/...> — is unchanged. Bump to 1.0.1.
