Support reading cli options  from config file

As we are adding additional cli options, it would become beneficial if we were able to define a .doctocrc.* file which contains the cli options reducing the need for these to be passed at command time.

These properties should mirror their cli equivalents. To help with this, argument handling should be switched to yargs as shown in https://github.com/yargs/yargs/blob/main/docs/advanced.md#rc-files
