Fixed-width input is always trimmed, regardless of trimValues setting

[geert3]

When reading a CSV with fixed width, white space is always trimmed. See CsvRawReader::parseFixedLine

values[i] = values[i].trim();

In my use-case, I have leading white space that should remain intact. I see several possible solutions:

• only trim trailing white space for fixed-width input
• trim white space only if 'trimValues' property is true (and perhaps make it true by default for fixed-width input)
