Expand $args array parameters that are described in other functions

Fixes #46. Needs testing.

Todo

• Check each of the ~60 additions to ensure they're correct
• Add inline docs so our future selves are thankful

strpos($description, '()')

Very clever.

This is looking good and we're green ✅ but I want to manually check each of the additions to ensure their correctness because there is an allowance for the parameter names to differ from its inherited function, which could in theory result in the wrong parameter being used.

Thank you!
