Make list scheduler work for different latency offsets

B-ASIC currently has support for specifying different latency offsets for operations as can be seen in the following example.

https://da.gitlab-pages.liu.se/B-ASIC/examples/lwdfallpass.html#sphx-glr-examples-lwdfallpass-py

The schedulers should be able to function for these cases.

added Scheduling label

assigned to @simbj106

changed title from Make list scheduler function for different latency offsets to Make list scheduler work for different latency offsets

mentioned in issue #279

Should be done at the same time as #279 since that will yield an FFT structure with these kind of operations.
