add C array arguments in the storeChunk() function API

[denisbertini]

** My problem ** My reading procedure is implemented via Fortran C interface. The interface exposes on static C arrays and i need to copy the C arrays to std::vector to use the storeChunk() function. I would like to avoid the additionnal copying of the data arrays ( these are huge array holding particle data!)

** Possible solution ** add C static array as argument of the storeChunk()

This WIP PR adds these calls. Until then, you can use storeChunk(shareRaw(ptr), offset, extent) to hijack the shared_ptr overloads.

what is the shareRaw() function exactly doing ?

[franzpoeschel]

It creates a shared pointer from a raw pointer with a no-op destructor, i.e. a non-owning shared pointer.

template <typename T>
std::shared_ptr<T> shareRaw(T *x)
{
    return std::shared_ptr<T>(x, [](T *) {});
}
