Add Ethernet.setHostname method and make DHCP hostname configurable.

0197eb7

- Added Ethernet.setHostname(const char* hostname) method. - Increased DHCP buffer size to 64 bytes to accommodate variable hostname length. - Updated DhcpClass to use the custom hostname.

Add DhcpCustomHostname example

40406cc

This example demonstrates how to use the `Ethernet.setHostname()` function to set a custom hostname for DHCP requests. It is based on the `DhcpAddressPrinter` example.
