Lb2Lll angular additional muon MC samples

Adding newly produced phase space MC for 2018 and Jpsi and Psi2S KS backgrounds needed for the mass fits. Pipeline run successfully after removing some typos, that took a while to hunt down. Due to the delay decided to also add electron MC samples (phase space, physics and backgrounds for the rare, Jpsi and psi2S mode). This was the last pipeline test running. Submitting merge request after test was run successfully. (Old samples with electron mode failed due to faulty DEDX tuple tool, which has been completely removed.)
