Calculate pupil speed using finite differences

Computes the speed of pupil changes using finite differences between consecutive time points. This is a helper function for the detransient step.

speed(x, y)

`x`	A numeric vector of pupil data
`y`	A numeric vector of time data

A vector of pupil speeds at each time point
