/// GsymReader is used to read GSYM data from a file or buffer.
///
/// This class is optimized for very quick lookups when the endianness matches
/// the host system. The Header, address table, address info offsets, and file
/// table is designed to be mmap'ed as read only into memory and used without
/// any parsing needed. If the endianness doesn't match, we swap these objects
/// and tables into GsymReader::SwappedData and then point our header and
/// ArrayRefs to this swapped internal data.
///
/// GsymReader objects must use one of the static functions to create an
/// instance: GsymReader::openFile(...) and GsymReader::copyBuffer(...).
