Bug#1058661: dipy: slow (sometimes timing out) autopkgtest

[Rebecca N. Palmer]

Package: python3-dipy
Version: 1.7.0-4

This autopkgtest, and particularly test_reconstruct_rumba, is slow 
enough that it sometimes times out and fails.  I think this is varying 
hardware speed and not a random hang because failure seems to correlate 
with the earlier tests taking longer.

This could be fixed by skipping some slow tests (-k 'not 
test_reconstruct_rumba').  Alternatively, if these tests are important 
it _may_ be possible to increase the time limit.
