CFITSIO.jl

• Function names closely mirror the C interface (e.g., fits_open_file()).
• Functions operate on FITSFile, a thin wrapper for fitsfile C struct (FITSFile has concept of "current HDU", as in CFITSIO).
• Note that the wrapper functions do check the return status from CFITSIO and throw an error with the appropriate message.
