132ea89c32 cdc: add extract_changes function 
This commit introduces a bunch of new structs describing a change made
to a table, and an `extract_changes` function which takes a mutation and
returns the set of changes contained in this mutation, separated by
timestamp and ttl.

b5c944370e cdc: add should_split function 
The function checks if there are multiple timestamps and/or ttls inside
a mutation, which means separate changes should be created for this
mutation in CDC.
