Proposal for an API change for the Get method

[gaissmai]

func (t *Table[T]) Get(addr netip.Addr) (lpm netip.Prefix, ret T, ok bool)

Often it is not only the value that is interesting but also the longest prefix that matched. Or maybe you add a Lookup() method:

func (t *Table[T]) Lookup(addr netip.Addr) (lpm netip.Prefix, ret T, ok bool)
