Trying to annualize records in the PAGE2k database - Error 'year 0 is out of range' #5

Code to reproduce:

pdb.annualize()

Using the example from: https://fzhu2e.github.io/cfr/notebooks/proxy-ops.html

There are long records beyond year 0. The function utilizes datetime that doesn't support year 0. So we need to preprocess the database and truncate the time period to be starting from year 1. This can be achieved by calling ProxyDatabase.slice([1, 2000]).
