Cleanup analysis script

[peterdesmet]

FINALLY! 😅 The analysis script to generate the tables and figures for Maes et al. 2019 is now working again + cleaned up:

• Using newly structured data
• Only writes minimal interim data
• Only includes necessary code
• Creates table 1 and 3, fig 2 and 3 of paper in reports
• Is now reproducible

We can finally claim this analysis is reproducible!
