The code examples in README.md are outdated

In the "Quick Start" section, this lines fail to compile:

    // Initialize reader
    CSVReader *reader = csv_reader_init_with_config(&arena, config);

The method csv_reader_init_with_config() now takes 3 parameters, the first 2 being pointers to Arena class. What is the difference between the persistent and the temporary arena?

I see that with the latest commit (91e1515, "add temp arena and set to be self owned or not") in test_csv_reader.c the calls to csv_reader_init_with_config() have been replaced with csv_reader_init_standalone(). An Arena object is still created in line 25, and used to allocate the CSVConfig object. This way, we end up having 3 Arenas, right? The other 2s are created and owned by the CSVReader. Just wondering if this is the best practice...

Can Arena objects be reused? It seems that the answer is no. I have created 2 Arenas. I use the first one to create config objects and as a persistent Arena for CSVReader objects, and the second one as temporary. Then I iterate all the .csv files in a directtory and for each of them I use the Arenas to create a config and a Reader, then free the config and the reader. After a few files, the arenas return NULL.
