Unittests for SPDHG take long time #1496

Unittests for SPDHG are done with the ASTRA cpu projector and on relatively large data, taking long time. We should reduce the amount of data that is processed.

test_SPDHG_vs_PDHG_explicit and test_SPDHG_vs_PDHG_implicit are particularly slow. The assert_almost_equal on such a large array is probably one of the biggest costs.

Thanks Gemma - have added this comment to #1644 PR which attempted to fix the slow tests
