Add suffixes like Ms and Ns to variables whos time unit is not in
seconds. This is aligning with a new code style of putting units
on variables that are not in SI base units.
Refactor away the config group concept and simplyfy the way config
fields are defined. Fields are defined directly as properties of the
static field fieldDefinitions on the class itself with a separate
interface to declare the types of fields.
This makes it possible to easily make accessing the config fields type
checked in a way that lets plugins extend the interfaces with their own
config options by adding additional fields to the interface via
declation merging.
Refactor the Config and ConfigGroup classes to match the JSON data class
pattern with toJSON, toRemote and fromJSON methods replacing the load,
init, and serialize methods. Since fromJSON requires extra information
the messages structures passes around the plain JSON representation of
the configs instead of serialising instances of the config classes
automatically.
