May fix pipeline failures on ghactions where makeico or toarray just exit with a non-zero status for no reason. Also makes it easier (possible, rather) to build TPT using a cross-compiling msvc toolchain on windows; you can't have two different msvc toolchains in PATH on windows because of course you can't. toarray had been python before, maybe I converted it to cpp to avoid pulling in python as a dependency, I'm not sure. With android vanilla development (hopefully) gaining traction soon, we'll be relying anyway on helper scripts I've written in python, so python will be a dependency sooner or later. Meson implicitly makes python a dependency, but there could be Meson implementations out there that don't rely on python, who knows.
