Describe the bug
Block size is inexplicably divided by 8 before printing, reporting 512bytes on my SE2 (iOS26 and iOS18). Block size on a modern iPhone is 4096 bytes.

To Reproduce
../go-ios/go-ios diskspace --address ... --rsd-port ...

Smartphone (please complete the following information):
SE2, iOS26, SE2 iOS18

Current output:

      Model: iPhone12,8
  BlockSize: 512
  FreeSpace: 36.7GB
  UsedSpace: 27.3GB
 TotalSpace: 64.0GB

Actual source code in main.c:

                fmt.Printf("  BlockSize: %d\n", info.BlockSize/8)

iOS uses apfs since 2017

Minimum block size on apfs is 4k:
