minor fix to change behavior of IP sweep in unicast

[nitin710]

Description

Minor fix to the protocol for IP sweep in unicast EmotiBit IP search. Expected IP sweep

for a emotibitCommSettings.json file with contents
      "sendAdvertisingInterval_msec": 1000,
      "checkAdvertisingInterval_msec": 100,
      "transmission": {
        "broadcast": {
          "enabled": true
        },
        "unicast": {
          "enabled": true,
          "ipMax": 254,
          "ipMin": 250,
          "nUnicastIpsPerLoop": 3,
          "unicastMinLoopDelay_msec": 3

expected behavior is as shown below:

Ping begin
<send Broadcast>
<start unicast pinging>
ping 250
ping 251
ping 252
<wait 3 m secs>
ping 253
ping 254
<wait 1000m secs>

in case of multiple networks

Ping begin
<send Broadcast>
<start unicast pinging>
ping x.x.x.250
ping x.x.x.251
ping x.x.x.252
<wait 3m secs>
ping x.x.x.253
ping x.x.x.254
ping y.y.y.250
<wait 3m secs>
ping y.y.y.251
ping y.y.y.252
ping y.y.y.253
<wait 3m secs>
ping y.y.y.254
<wait 1000m secs>
