Usage:
m := partmap.NewPartitionedMapWithDefaultPartitioner(3) // 3 partitions
if err := m.Set("key", 123); err != nil {
panic(err)
}
value, err := m.Get("key")
if err != nil && !errors.Is(err, partmap.ErrNotFound) {
panic(err)
}
println(value) // 123
if err := m.Del("key"); err != nil {
panic(err)
}
