Eddie Hebert 314b22656f MAINT: Remove left over simple transform code.
Remove pieces that are no longer used now that the simple transforms are
wrappers around history via the SIDData object.

Move window length related pieces into batch_transform, since the rest
of the utils module is no longer used.
