Baseline crossing updated

Re-running the baseline crossing analysis with up-to-date data

@SHSRPL, I noticed an error in the baseline minting function (my mistake!), where we were not getting the latest value of the baseline function. I fixed it by getting the data from Starboard, and I rerun the notebook.

The TLDR is that the Baseline Crossing dates are much earlier now with the new onboarding rates. The base scenario points to a baseline crossing event occurring in March 2023.
