Found with gcc's -Wmissing-declarations which gives warnings like
../src/tinyexpr.cpp:61:5: warning: no previous declaration for ‘int get_arity(int)’ [-Wmissing-declarations]
61 | int get_arity(const int type) {
The same warnings show up for builtin functions like builtin_bg because they
currently don't include their own headers. I left that.
Also reformat the touched files.
