niffler_precompiled/platform

Platform detection and NIF version compatibility.

The normalization rules mirror what rustler_precompiled does for Elixir: OTP reports a system architecture triple that is close to, but not always equal to, a Rust target triple. Windows is the main special case (“win32” for both 32- and 64-bit OTP), and macOS appends a kernel version to the OS component.
