Computes the Starkware version of the Pedersen hash of x and y.

|
The hash is defined by:
|
||
|
|
shift_point + x_low * P_0 + x_high * P1 + y_low * P2 + y_high * P3
|
||
|
|
where x_low is the 248 low bits of x, x_high is the 4 high bits of x and similarly for y.
|
||
|
|
shift_point, P_0, P_1, P_2, P_3 are constant points generated from the digits of pi.
