alternative defintion of slice and coslice as extension types #69

Define coslice' A a and slice A a as extension types (arrows in A with start/end a) and compare them to previous version (defined as total types of representables).

Merging now but @TashiWalde is there an rzk issue you wanted to raise about the η-reduction?
