#118 Incorrect capture duration reported

After finishing analyzing and storing the statistics of the pcap file in 1, the reported duration is wrong. The reported statistics are:

PCAP FILE STATISTICS SUMMARY  ------------------------------
Total packet count:     78329145 packets
Recognized packets:     78329145 packets
Unrecognized packets:   0 PDUs
% Recognized packets:   100.0 %
% Unrecognized packets: 0.0 %
Last unknown PDU:       None
Capture duration:       0.4295 seconds
------------------------------------------------------------

Examining the database in query mode, we can see:

SELECT timestampLastPacket FROM file_statistics;
Query returned 1 record:

+----------------------------+
| timestampLastPacket        |
+----------------------------+
| 2018-04-04 07:15:00.331786 |
+----------------------------+
> SELECT timestampFirstPacket FROM file_statistics;
Query returned 1 record:

+----------------------------+
| timestampFirstPacket       |
+----------------------------+
| 2018-04-04 07:00:00.448274 |
+----------------------------+

Fixed. Merge into master coming with SMBScan fixes.

Fixed in commit 971df14819.

EDIT: Off-by-one-second error fixed in pull request #131.
