Decrease doubleclick dependency size

[MartyHub]

What do you want to change?

• github.com/sqlc-dev/sqlc/cmd/sqlc has now a dependency on github.com/sqlc-dev/doubleclick
• size of github.com/sqlc-dev/doubleclick Git repository is ~500Mo:

~/go/pkg/mod/github.com/sqlc-dev $ du -sh doubleclick@v1.0.0
509M    doubleclick@v1.0.0

=> using github.com/sqlc-dev/sqlc/cmd/sqlc as a Go tool (tool github.com/sqlc-dev/sqlc/cmd/sqlc in go.mod) will fetch 500M of data, even if dependency is not required

This could be annoying in CI and Docker images

Is there any way to improve this situation?

The issue is that github.com/sqlc-dev/doubleclick/parser/testdata is 500 MB.

In order to prevent this from being included in the module zip, it needs to be made into a nested module. (For example, github.com/sqlc-dev/doubleclick/parsertest or github.com/sqlc-dev/doubleclick/parser/parsertest)

It depends on what Kyle wants to do.

The testdata isn't included in the compiled binary, so I'm okay with the status quo. In the future, I'll be adding a Go API. That will make it easy to only include the engines that you use.
