• Support more types of the formVec<primitive_type> and ZeroCopyBuffer<Vec<primitive_type>>, such as Vec<f32> and ZeroCopyBuffer<Vec<f32>> to be transformed into Float32List in Dart. (#162, #153)
• Do not generate unnecessary Dart to Rust wire code to fix bugs such as when Vec<ZeroCopyBuffer<Vec<u8>>> is in output argument.
• Warn when ffigen emits any [SEVERE] log messages.
• Make outputs change less when input of codegen changes.
• Simplify Wire2Api<Option<T>> generated code.
