-- This function takes a JSON5-formatted string, parses it, then deserializes the
-  result into a `Keyboard` object.
-- [JSON5](https://json5.org/) is a simplified / lenient version of JSON that is
-  easier for humans to type; in particular, it doesn't require quotes around
-  property names. Any valid JSON string should also be a valid JSON5 string.
