Something went really wrong with the merge at e0e8c0d3. As a result, changes made by @dave where reverted in the merge. This commit restores those changes

h2_vs_hs2: added more sensors, more general form of the blade distributed parameters obtained for HAWC2 statistics, other small fixes

hawcstab2: induction output file number of columns depends on the version of HAWCStab2. Assume 38, but fallback to 34

some of the continued work on h2_vs_hs2 was done in the old prepost instead of the new wetb: updated plots, more comparison cases

more PY2 vs PY3 differences that required a change: new line character is 1 char in PY3, passing dict as kwargs when calling a function
