Call events log is missing a quote character, outputting malformed csv

[profporridge]

When I enable logging of a DMR system's call events the resulting file is missing a quote character, which makes parsing the log difficult. Sample attached. The issue seems to be in the 'Timeslot' column.

This is on 0.5.0 alpha 06

Also seeing this behavior.

0.5.0 Alpha 6 - MacOS

Was planning on using the logs to help identify and tag a local trunk's TGs and Radios programmatically, but malformed CSV is troublesome.

I think this line :

sdrtrunk/src/main/java/io/github/dsheirer/module/log/DecodeEventLogger.java

Line 150 in 75ef321

sb.append(",\"TS:").append(event.getTimeslot());

is missing a .append("\"")

I'd file a PR for it, but I'm not a java dev and dont have an environment to build and test with.
