Removed unneeded debug logging of the `CommentBlockLine`

[Darius-Wattimena]

Retrieving an AIS message using the AisTcpReader will always result in the command block being put in the console. When looking deeper into the code of CommentBlockLine, it seems that the content is always logged at the parse method. This didn't seem correct, so this line removal will fix this unneeded spamming of the console.

This is greatly welcomed. It’s spamming down our logs.

@dimitrispallas any plan to get this merged/released? logs are filling up quickly.

Time to look into Java Logging I guess (https://www.baeldung.com/java-logging-intro) 🙈
