2021-01-14EnergyTrace drift compensation: optimize via shortest pathsDaniel Friesel-72/+88
Right now performance is worse than the previous greedy approach as the dijkstra variant does not take into account that a transition may be missing from the set of detected changepoints (i.e., it assumes that the set of detected changepoints contains the transition timestamp, which is not always the case). This will be fixed in the next commit by adding nodes for the expected transition timestamp (with a slightly higher weight to ensure there are no proper nodes in the vicinity) -- or something similar.

2020-12-14energytrace: add pelt-based drift compensation experiment.Daniel Friesel-6/+140
Enable with DFATOOL_COMPENSATE_DRIFT=1 so far it's pretty unreliable.

2020-12-03use common energytrace loader codeDaniel Friesel-102/+73
this also fixes a nasty off-by-one in the barcode loader (now _load_energytrace): wrong: interval_start_timestamp = data[:-1, 0] * 1e-6 correct: interval_start_timestamp = data[1:, 0] * 1e-6
