BUG: String parsing in vtkDelimitedTextReader
BUG: String parsing in vtkDelimitedTextReader

When using string delimiters, any content (usually whitespace)
between the start of a field and the start of a string delimiter
should be discarded.

Previously, the line:
  '1, "word",2'
was parsing to:
  "1"; " word"; "2"
it will now parse to:
  "1"; "word"; "2"
