Small correction: RFC 8520 actually states in section 10.1 that "[i]n the case where both v4 and v6 DHCP options are emitted, the same URL MUST be used." Using the same macro therefore enforces this constraint.

This PR introduces support for the Manufacturer Usage Description (MUD, RFC 8520) by integrating the option for DHCPv4 and DHCPv6. When activating the feature, a MUD URL options will be integrated into DHCP requests and DHCPv6 Info Requests, respectively.

As it is recommended that only one MUD URL is used per device, I used the same macro definition for inserting the URL into the respective functions for both DCHP and DHCPv6.

I was not entirely sure how to contribute a test case for the two options, if you have any suggestions in this regard, let me know!
