Crash with checks on large protocol buffers

[elliotmr]

I just updated to the latest version of assert and it seems to be causing havoc on our CI/CD system. The problem is that we have several checks on large protocol buffers. The private state member is then rendered through the repr reflection system and it can be hundreds of thousands (millions?) of lines.

• Did the default behavior of printing private members change recently?
• Is there some way that I can globally disable showing private members in the assert library without having to pass extra arguments to every assert call?
