Detailed Description

Converts direct style function to cps functions.

To do so, for each (non-type-level) ds function a corresponding cps function is created:

f:     [a: A] -> B
f_cps: Cn [a: A, Cn B]

Only the type signature of the function is changed and the body is wrapped in the newly added return continuation. (Technical detail: the arguments are substituted to fit the new function)

In a second distinct but connected step, the call sites are converted: For a direct style call f args, the call to the cps function cps2ds_dep ... f_cps args is introduced. The underlying substitution is f -> cps2ds_dep ... f_cps.
