Memory dependencies do not consider the block terminators

[antalsz]

Consider the following program:

DECLARE ro BIT

MEASURE 0 ro
JUMP-WHEN @eq ro
LABEL @eq
RX(pi/2) 0

This program ought to have a memory dependency from the MEASURE 0 ro to the JUMP-WHEN @eq ro, and from the JUMP-WHEN @eq ro to the RX(pi/2) 0. However, the JUMP-WHEN becomes a block terminator, and block terminators do not show up in the quil_rs::program::scheduling::DependencyGraph, so there is no dependency between the MEASURE and the JUMP-WHEN.
