Implement waitReadable and waitByteTime on Windows #269

Open mrchipset opened 2 years ago

mrchipset commented 2 years ago

In order to implement timeout function of waitReadable, MS Asynchronized I/O feature is introduced with FILE_FALG_OVERLAPPED flag of CreateFileW method.

Both read and write method have been refactored to support asynchronized I/O.

I have briefly tested it with test_serial subproject. It seems work fine. Looking forward to more testing.
