Make transformers show warning or exception when there is mismatch between number of series used for fit() and and transform()

[hrzn]

see #1288.

• We should raise a warning or even an exception when we have a mismatch in number of series used for transformer.fit() and transformer.transform()
• we could also add a mappable or indices of the specific series we want to transform

[madtoinou]

This should be solved by #1409, which implements a mappable to match the fit() and the transform() series and raises an error in case of mismatch code snippet
