Try to not crash when opening invalid files. Tracy will now perform a number of checks when trying to read a dump file: 1. The file must have at least 4 bytes of data. 2. There should be a 4 byte header to indicate the file was saved by tracy. This is a breaking change in file format. 3. Old header-less files are still supported, but there's a new check for data validity. The first 4 bytes of file (as an uint32) must be less or equal to max LZ4 data packet size. This requires the first two bytes to be 00 00 or 00 01, which should catch most invalid files. 2018-04-21 12:53:40 +00:00			`#ifndef __TRACYFILEHEADER_HPP__`
