Faster then writing to std map.

Usage:

m := partmap.NewPartitionedMapWithDefaultPartitioner(3) // 3 partitions
m.Set("key", 123)
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)
}
