Support render template

the whole encrypted sops may contain a lot of secrets, but most of time only need piece of it, hope sops support some template render function, like

create user test login password '{{.pg.users.test.password}}';

sops secrets.yaml --output template=in.sql > out.sql

the out.sql should be

create user test login password 'xyz';

This can also used as inline template

sops secrets.yaml -o go-template="create user test login password '{{.pg.users.test.password}}';"  > out.sql

The output should be the same

The issue provides no repository files or tests; start by tracing the Go CLI path for encrypted-file output and reviewing how sops parses and exposes decrypted values. Use the file-template and inline go-template examples as the acceptance cases, with both producing the shown SQL output.
