Add whatrecord template for generating files based on parse results

[klauer]

Idea

"pytmc template" offers the ability to take a parsed TwinCAT project, a Jinja template, and generate documentation and such based on those files.
I would like to have a whatrecord template tool that does something similar.

In a pseudo bash line of sorts:

$ whatrecord parse my_file.db --json | jinja-template-tool my_page_format.template > output.html

Context

• whatrecord could generate files in any format convenient for the user
  • Create HTML docs from a database file
  • Write linter results in a more user-friendly form
  • Transform file formats
  • etc.
• I'm thinking that all of the above could be useful for our IOC CI.
