	Do not attempt to construct own meta data.
	Set Endian and Word size for data read from elf header.
	(CorefileByteBuffer(File)): Build own meta data.
	(peek): Rewrite. Navigate provided meta data to find the peek
	offset and the file name of that offset.

	(isFileSane): Simplify. Check for null on backing
	corefile.
	(findMetaData): New. Consolidate all meta data look-ups
	here.
	(checkCorefileAddress): New. Answer whether this data is in the

	(isExeProvided): New. Return whether exe backing is provided.
	(getDynamicSegmentAddress): New. Return tuple of core file
	dynamic segment address and size.
	(getExeDynamicSegmentAddress): New. Get backing exe dynamic segment's
