Add functionalities to manage SRv6 SID formats (register / unregister / lookup) and create two SID formats upon SRv6 Manager initialization: `uncompressed-f4024` and `usid-f3216`. In future commits, we will add the CLI to allow the user to choose between the two formats. Signed-off-by: Carmine Scarpitta <cscarpit@cisco.com>
