[FIX] payment_sips: accept scoreInfo in payment response

After a payment is processed by SIPS, a data object is posted back
to Odoo. The data has a `ScoreInfo` element that has more than one
`=` characters (e.g. `scoreInfo=A3;N;N#SC;N;TRANS=3:2;CUMUL=4500:250000`)
This causes the method `_sips_data_to_object` to break, because there
will be too many values to unpack.

To fix this, we should limit the data split to 2 values. This is the
same method used by SIPS to process data as well.
