4.2.2

Minor Analysis Improvements

• We no longer track taint into a sync.Map via the key of a key-value pair, since we do not model any way in which keys can be read from a sync.Map.
• database source models have been added for v1 and v2 of the github.com/couchbase/gocb package.
• Added database source models for the github.com/Masterminds/squirrel ORM package.
