Summary: This patch just bumps the histpack version number to 1 and adds a config flag to enable writing v1 pack files. The format hasn't actually changed in this patch, I'm just doing the verison bump so I can update all the hashes in the tests without working about functionality change. In the next patch I will modify the index format, which won't affect the hashes. Test Plan: Ran the tests. I also ran the tests with some debug code to manually force the sha to include 0 instead of 1 and verified that the hash didn't change (which confirms that all of these hash changes are just because of that one byte version change).
