host_num attribute

[carmine73]

First of all, thanks for this great provider.
It would be nice to have one more attribute host_num that shows the host number inside the network, to be used with the terraform cidrhost function

Terraform Version

Terraform v1.0.0
on linux_amd64
+ provider registry.terraform.io/volcano-coffee-company/cidr v0.1.0

Terraform Configuration Files

locals {
  my-net = {
    ip   = "192.168.1.131"
    mask = "255.255.255.128"
  }

data "cidr_network" "my-net" {
  ip    = local.my-net.ip
  mask  = local.my-net.mask
}

output "my-net" {
  value = data.cidr_network.my-net
}

Expected Behavior

  + my-net          = {
      + broadcast = "192.168.1.255"
      + first_ip  = "192.168.1.129"
      + host_num  = 3
      + id        = "192.168.1.128/25"
      + ip        = "192.168.1.131"
      + last_ip   = "192.168.1.254"
      + mask      = "255.255.255.128"
      + mask_bits = 25
      + network   = "192.168.1.128/25"
      + prefix    = "192.168.1.131/25"
    }
