Add support for more than 4 columns in the csv file in CsvGraphStorageBuilder

[redfrexx]

Requests with extra_info": ["csv"] fail because the csv file contains more than 4 columns. Can we add support for more than 4 columns?

@redfrexx Please elaborate a bit more in detail why this change is needed, for documentation purposes. Thanks :)

For the HEAL routing client we provide 5 points in time: now and 4 timestamps of a typical heat day (10am, 1 pm, 4pm and 7pm). So that makes 5 columns in the csv file.

Ideally and if possible with reasonable effort, it would be good if even up to 8 or 10 columns could be supported to conduct further route analyses, e.g. provide heat indices for several months to see how the detours evolve across the year compared to the fastest route.

I have looked through the code and didn't find an indication that this limit is in place. Can you provide some details that show that this limit exists?

Request work, but when adding extra_info: ["csv"] to the request, I get the error:

ERROR [routing.RoutingProfile] - java.lang.ArrayIndexOutOfBoundsException: arraycopy: last destination index 18 out of bounds for byte[4]
