Returns the BaseType of the Tinput, i.e the base type without extra props, but maintaining the same type, including the Type of any Nested values.

Optionally, you can pass TypeChange to change the type of the BaseType's Nested values (or in case of Primitives, the type of the returned value itself). Eg a Tinput = Array<'foo'> will return Array<'bar'> if you use BaseType<Tinput, 'bar'>, it will return Array<'bar'>,changing the Nested values type to 'bar'.

It's used to exclude the BaseType props from the instance props and calculate what to return when map()-ing values.
