[HOT] Analysis of when mappers joined OSM

[Rory McCann]

One "simple" way to know when a user started editing is download the
full history file as XML, not PBF, and look for the first changeset made
by a mapper.

The account_created on the user details will tell you when the account
was created, and normally they start editing shortly afterwards, but
there are a tiny amount who only start editing years after creating an
account. e.g. https://www.openstreetmap.org/user/SimonPoole/diary/34856
