Create 'latest' symlink(s) when materializing schemas
Created by: ottomata
Add new shouldSymlinkExtensionless that if true, create's both latest.(json|yaml) as well as an extensionless 'latest' symlink (if configured to do so) when materializing schemas. This symlinks will only ever be updated if jsonschema-tools materializes a schema that has a greater version than the version of the schema that the latest symlink currently points at.
