add C array arguments in the storeChunk() function API

** 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()`
