Q: Write a function to verify if a given set of interfaces is present as next-hops for a given prefix in router's routing table.
Task:
* Implement function: check_prefix_next_hops("router-1", "216.182.232.249/32", ["bond1", "bond3"])
* Function must return True/False
* Use example router output from MOCKED_DEVICE_DATA object
MOCKED_DEVICE_DATA = {
"router-1": """
B>* 216.182.232.249/32 [200/0] via 100.92.0.1, bond1, 00:14:14
* via 100.92.0.3, bond3, 00:14:14
C>* 253.4.0.232/31 is directly connected, jrp2-1
B> 30.0.0.0/8 [200/0] via 100.92.188.32 (recursive), 00:00:25
