Add ability to replace clump model with atomic and vice-versa

[FileEX]

Fixed #3699

Until now, when replacing an atomic model with a clump model, only one atomic was visible in the game. On the other hand, when replacing a clump model with an atomic model, the function would either return false or cause a crash.

Now MTA also supports replacing clump-type objects. However, to maintain backward compatibility, models are not automatically converted based on the number of atomics. If you want to replace an atomic-type object with a clump-type object, you need to convert it using the function below

Syntax

bool engineConvertModelToType(number modelId, string modelType)

• modelType: object (atomic) | damageable-object | timed-object | clump.

Once this PR is merged, the next item on my to-do list is object animations.

-- ATOMIC -> CLUMP
local dff = engineLoadDFF('nt_windmill.dff');
engineConvertModelToType(1337, 'clump');

engineReplaceModel(dff, 1337);

-- CLUMP -> ATOMIC
local dff = engineLoadDFF('binnt07_la.dff');
engineConvertModelToType(3425, 'object');

engineReplaceModel(dff, 3425);

Is it possible to use a general solution?

engineConvertModelToType(modelId, "ped" | "vehicle" | "object" | "timed-object" | "clump" | "object-damageable")

It looks like automatic conversation may break some models.
And i don't think that somebody will be happy, when 'timed-object' converts to 'object' or 'clump' silently.

Yes, you're probably right. This could be backwards incompatible in some way, and additionally, automatically 'guessing' the model type is quite problematic and results in more complex code. I think this solution is appropriate, allowing the user to define which model type should be created

I added engineConvertModelToType to convert the model to another type (atomic, clump, damageable-atomic, timed object). I tested this in many different variations to eliminate as many crashes as possible. I think the PR is ready, as I haven't observed any new crashes. The default behavior is the same as before, meaning only one atomic is replaced

bool engineConvertModelToType(number modelId, string newType = "object" | "timed-object" | "damageable-object" | "clump")
