Tracking change in data schema over time

[tnwei]

The data schema in this repo, i.e. the columns in CSVs change over time as the pandemic response evolves. Example: commit a6ccca9 renames columns for dose1 and dose2 to daily_partial and daily_full, to incorporate the rollout of single-dose vaccines. Although this is natural for pandemic data collection, it can be disruptive to downstream data consumers, who had to modify their applications to keep up with the changed data schema.

I'm keeping track of the data schema changes at https://gist.github.com/tnwei/6b1e974ff0fa5463933c94964a831dd0, which is updated regularly. Would like to suggest linking to my list in the README, so data consumers can see the lineage of data schema changes.

I'll put in a PR if @CITF-Malaysia is onboard. TQ for your tireless data updates!
