Description
It seems difficult to use them for valid loads/stores, but we can adapt the `BadLoadStore` generator to pick them more often.

Research direction
Start with the otbn DV code for the BadLoadStore generator and the enc_s_cg coverage point. Adjust the generator so extreme offset values are selected more often for valid loads and stores, then run the relevant OTBN DV tests and confirm that coverage reaches those values.
