There are two new load commands added in 10.15 / iOS 13 (http://newosxbook.com/articles/13-10.15.html and can be seen in /Applications.Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/mach-o/loader.h:324

#define LC_DYLD_EXPORTS_TRIE (0x33 | LC_REQ_DYLD) /* used with linkedit_data_command, payload is trie */

#define LC_DYLD_CHAINED_FIXUPS (0x34 | LC_REQ_DYLD) /* used with linkedit_data_command */

This is blocking usage of macholib on any recent binary, good time to reference issue #26

I'm not yet sure of the extent or necessity of these new load commands.
