Invocation: simplify and unify type decision logic

Browse source 
Now reaping the benefits of the ambitious refactorings done yesterday.
- Only retaining the basic distinction of the four use cases
- all further adaptation now directly based on the »lifted« types
- can even add quite stringent compile-time sanity checks.

Now the refactoring is on-par with the capabilities of the old downstream code,
which, btw, could be retained in compilable (yet not working) state. But the new
traits logic is already more capable and could accept tuples and arrays as well.

Next major topic to address is to provide the foundation for parameter handling.

/** Helper to pick up the parameter dimensions from the processing function
* @remark this is the rather simple yet common case that media processing
* is done by a function, which takes an array of input and output
* buffer pointers with a common type; this simple case is used
* 7/2024 for prototyping and validate the design.
* @tparam FUN a _function-like_ object, expected to accept two arguments,
* which both are arrays of buffer pointers (input, output).
/**
* Trait template to analyse and adapt to the given processing function.
* The detection logic encoded here attempts to figure out the meaning of
* the function arguments by their arrangement and type. As a base rule,
* the arguments are expected in the order: Parameters, Input, Output
* - a single argument function can only be a data generator
* - a binary function can either be a processor input -> output,
* or accept parameters at «slot-0» and provide output at «slot-1»
* - a ternary function is expected to accept Parameters, Input, Output.
* @tparam FUN a _function-like_ object, expected to accept 1 - 3 arguments,
* which all may be simple types, tuples or arrays.
* @note »Buffers« are always accepted by pointer, which allows
* to distinguish parameter and data «slots«
