Implement DictSquashCopyDict hint

[TAdev0]

This PR implements DictSquashCopyDict hint, which prepares arguments for creating a new dictionary with dict_new function. It copies the existing squashed dictionary in the current scope

Closes #292

@har777 i'm not 100% sure i'm implementing correctly this python code

dict(__dict_manager.get_dict(ids.dict_accesses_end))

could you check this?
I guess this code only retrieves from operanders the address dict_accesses_end , uses GetDictionary to retrieve the dictionary (a copy) and assign it in scope?

[MaksymMalicki]

could you resolve conflits? It will be easier to review ✅

[TAdev0]

@har777 @MaksymMalicki just updated, now making a deep copy of the ZeroDict before assign it in the new scope.
I added only one test for now with an empty dictionaryManager, will add other tests tomorrow

[TAdev0]

currently FreeOffset field of the ZeroDict struct is of type *uint64 , any reason?

[TAdev0]

@har777 ready for review, i think this is the last dict hint

[TAdev0]

i guess we should use FreeOffset uint64 in ZeroDictionary, there is no benefit of using a pointer here, we can modify this later

[har777]

You only need to copy the data. Not the entire ZeroDictionary. This variable is used in the DictNew hint in this same file. So just a copy of the Data field. Maybe some method like dictionaryManager.getDataCopy(dictPtr)?

[har777]

Or you can just create a copy of it it inline in this hint. Its not really used anywhere else.
