Using ; as CSV separator

[josegrad]

Excel uses ; as CSV separator in some configurations. Changing the separator in Excel is quite opaque.

This parser seems to accept only , as separator. It would be nice to support ; as well.
In any case for the parser to work you need to replace ; with , in the generated Excel.

Not a critical issue but it might help someone who gets a strange JSON generated after parsing CSV where ; are used.
