I have found a CSV parsing issue with FasterCSV (1.5.0) which seems like a genuine bug, but which I'm hoping there's a workaround for. 

Basically, adding a space after the separator (in my case a comma) when the fields are enclosed in quotes generates a `MalformedCSVError`.

Here's a simple example:

```
# No quotes on fields -- works fine
FasterCSV.parse_line("one,two,three")
=> ["one", "two", "three"]

# Quotes around fields with no spaces after separators -- works fine
FasterCSV.parse_line("\"one\",\"two\",\"three\"")
=> ["one", "two", "three"]

# Quotes around fields but with a space after the first separator -- fails!
FasterCSV.parse_line("\"one\", \"two\",\"three\"")
=> FasterCSV::MalformedCSVError: Illegal quoting on line 1.

```

Am I going mad, or is this a bug in FasterCSV?
