Ramda sync and async promises using pipeP

/**
 * Similar to `pipe` and `pipeP`, but this method allows interpolation of
 * async and sync functions by preceding all the passed in functions with a
 * resolved promise. All functions must be unary (unlike the first argument
 * of it's sister functions).
