also: - fixed some parsing and printing ops being locale-dependent (fixes #19) - fixed pkgconfig subdir being wrong (fixes #23) - fixed some parsing errors at EOF when `TOML_EXCEPTIONS = 0` - fixed some unreferenced variable warnings on older compilers - fixed some 'maybe-uninitialized' false-positives on GCC9 - added debug/release awareness to CI tests - added locale awareness to catch test runner
