Crashing on options in the reserved space

[SibertDekimo]

The DHCP crashes when a DCHP-request is sent with options in the 224-254 range.
According to iana, this space is reserved for private use. Microsoft happens to use this range (249 for classless static route), which makes the DHCP-server incompatible with my OS, Windows 10.

I have fixed this by editing line 206 in dhcp.js:
this.emit('error', 'Unknown option ' + req);

becomes

if(!(req >= 224 && req <= 255))
{
	this.emit('error', 'Unknown option ' + req);
}

I don't know if this is the correct/best solution, but it works for me.
