- Adding attribute helpers for manufacturing and non manufacturing attributes as well as all attributes irrespective of manufacturing specification
- Incrementing the attribute largest return by 1 since that is how our embedded code assumes it
- Bumping the feature level point

Properly implement attribute importing with multiple lists, instead of recreating new attribute every time.

Properly hand output file to the conversion, so that the package file relativity is calculated correctly.

Encode some JS truthiness concepts into a unit test, since we seem to have a problem of converting '0' from db into a truthy value.

Support {name} and {basename} substitutions for auto-conversion, so SDK upgraders have an easier job.

Modify IDE integration with Silabs Simplicity Studio: require apack level 8 and simplify duplicate files into a single file as a result.

- Adding a helper to get manufacturing and non-manufaturing specific cluster commands which are needed for parsing the commands
- Adding the correct logic to detect available commands for the command parser
