Exception occurs if dictionary file has CRLF

Version: Logstash 6.5.1(logstash-filter-translate-3.2.3)
Operating System: Linux

Config File (if you have sensitive info, please remove it): config file like this:

input {
generator {
  lines => [ "100", "200", "300" ]
  count => 1
}
}
filter {
translate {
  field => "[message]"
  destination => "[dest]"
  dictionary_path => "/root/logstash/config/dic.csv"
}
}

dictionary file:

100,foo
200,bar
300,boo

Steps to Reproduce: An exception is raised if there is a CRLF in the dictionary file. After downgrading logstash-filter-translate from 3.2.3 to 3.1.0 or replacing CRLF to LF, everything works as expected.

Details: https://github.com/logstash-plugins/logstash-filter-translate/blob/master/lib/logstash/filters/dictionary/csv_file.rb#L20 @csv.shift returns this error if line has \r\n as eol.
Workarounds:
1. replace dictionary file's eol from \r\n to \n This workarond is no impact to current code.

strip \r\n https://github.com/logstash-plugins/logstash-filter-translate/blob/master/lib/logstash/filters/dictionary/csv_file.rb#L19 @io.string = line ⇒ @io.string = line.strip
