update to latest hessio library

[kosack]

The latest hessioxxx library is needed for reading the latest sims, so we should update the version inside pyhessio.

@kosack Could you please provide one of these lasted sim file that need the new hessio library for test purpose ?

[kosack]

That's a good question: I'll ask if Gernot can provide one - I think the prod3b ones are still readable, but the next production may need the updated library to access the new information stored in them (the current info should still be readable, since it is backward compatible).

At least you should test with a prod3b file from the grid. I plan on uploading on to our new shared webserver soon, but you can get one from the CTA-Grid web interface as well.

I am actually listening :-)

Do you just need a random file for testing? If yes, then I would try to find a small one. Do you have access to the GRID?

[jacquemier]

Yes, I have access to the GRID.

I believe that hessio library should be updated once again. I'm trying to read a recently produced sim_telarray file with pyhessio and I'm getting the following error message:

Unsupported camera definition version: 5.
Skipping telescope event sub-item of type 2032 for telescope 1
Skipping telescope event sub-item of type 2032 for telescope 1
...

I traced this back to the io_hess.c routine at https://github.com/cta-observatory/pyhessio/blob/master/hessioxxx/src/io_hess.c

...
item_header.type = IO_TYPE_HESS_CAMSETTINGS; /* Data type */
if ( (rc = get_item_begin(iobuf,&item_header)) < 0 )
return rc;
if ( item_header.version > 4 )
{
fprintf(stderr,"Unsupported camera definition version: %d.\n",
item_header.version);
get_item_end(iobuf,&item_header);
return -1;
}
...

In a recent version of hessioxxx I found instead

item_header.type = IO_TYPE_HESS_CAMSETTINGS; /* Data type */
if ( (rc = get_item_begin(iobuf,&item_header)) < 0 )
return rc;
if ( item_header.version > 5 )
{
fprintf(stderr,"Unsupported camera definition version: %d.\n",
item_header.version);
get_item_end(iobuf,&item_header);
return -1;
}

I attached a file for testing purposes.
