Fixing rtl_sdr.exe output binary mode on Windows

[williamyang98]

Issue: src/rtl_sdr.c doesn't set stdout to BINARY mode on windows.
This causes the output stream to be translated by Windows which causes:

• Specific byte values/sequences are interpreted and malformed
• The I/Q byte packing can fall out of sync due to removal/addition of bytes
• Streams closes abruptly because a EOF text character was sent

Fix: Line 291 in src/rtl_sdr.c
-- _setmode(_fileno(stdin), _O_BINARY)
++ _setmode(_fileno(stdout), _O_BINARY)
Changing stdin to stdout will actually set stdout to BINARY mode.
