Add the ability to sort inline tables and inline arrays

[jonathangreen]

This PR makes a few related changes:

• Optionally add the ability to sort inline tables and arrays (new switches added for this functionality: --sort-inline-tables and --sort-inline-arrays, which are implied by the --all option
• Add new options groups to the cli, to group the related formatting, comment, and sorting args
• Add some additional formatting checks
  • Make sure inline arrays and tables are consistently formatted
  • normalize the formatting for key = value pairs, always one space on either side of equals sign
  • Add switch to add trailing comma to multi-line inline arrays --trailing-comma-inline-array

Love it! Tested everything locally, code looks great, the consistency additions are much-needed, and the naming choices are fantastic. Thanks!
