v2.7.0 to permit sending data more than 2/4/8/16K

### Releases v2.7.0

1. Fix severe limitation to permit sending larger data than 2/4/8/16K buffer
2. Add examples [EthernetWebServer_BigData](https://github.com/khoih-prog/Ethernet_Generic/tree/main/examples/EthernetWebServer_BigData) to demo how to send larger data than 2/4/8/16K buffer
3. Optimize code
4. Clean up
5. Update `Packages' Patches`
