[WIP] refactor read_group set of functions to read data in arbitrary order

Browse Source 
This fix is required to fix backwards compatibility issue of TEXT back end. In the meantime, the custom garbage collector from generator_tools which was deallocating previously allocated memory (datasets and strings) is no longer valid here since the order of allocation can be atrbitrary. This requires a new custom garbage collector, maybe as a separate functions in TEXT back end
