v1.4.0 to support QNEthernet
### Major Release v1.4.0 1. Add support to [QNEthernet Library](https://github.com/ssilverman/QNEthernet) for Teensy 4.1 built-in Ethernet 2. Fix bug in non-blocking connection 3. Add new feature to permit using either server's hostname, such as `your_account.duckdns.org`, or server's IPAddress, such as IPAddress(192,168,2,112) 4. Update examples with new features, bug-fixes, etc.
