Can the library handle starting the validator server for the user?

For example, like wallaby starts chromedriver for you, and chromic_pdf starts chrome for you.

There are different ways of installing and running vnu. E.g.

• precompiled binary from brew/npm/pip
• .jar file, requires java installed
• docker image

Desired behavior:

• Nothing should change for existing library users. The library should not automatically switch to autostrating the validator server for existing users.
• It should be very easy for new users to let this library autostart the validator server.
• It should be possible for everyone to turn off autostarting the validator server.
• It should be possible to choose the desired command of autostarting the validator server.
• The changelog should mention migration instructions for people who would want to switch to autostarting.

Ports can be used to star a system process. This library would need to have its own supervision tree then. But only when autostarting the validator server for the user. Otherwise no processes are needed in this library.
