Tests S4015-S4021: Increased energy recovery using a new ERC

There was less energy recovery using Pulsotron-4 than using Pulsotron-3, so several tests were performed to fix that using configuration-2, so we improved in one test from 14.5% to 70%. That solution will be added to several others to help to generate more energy than used.

In the graph can be seen the old coil in blue and the new one that is grey. The other two plotlines correspond to other sensors:

Test S4015

We added some captures made during the tests:

S4018 captured using a high resolution camera
S4018 high speed capture

Fortunately, only a launcher was broken during tests that were replaced immediately
