Fix CompositeCOR default values
Following Elodie's feedback on Composite COR finder failing, default values of the CompositeCOR algo are modified to agree with those used on Night_rail, which seems to work.
@payno : part of the data to be changed are params and part are options. You can retrieve the options from CompositeCORFinder._default_cor_options
and the params of the Class with get_default_kwargs(func)
function (reputedly "inelegant" but could do the trick).
