darshan agg_perf_by_slowest estimate is incorrect

darshan-parser attempts to estimate shared file I/O performance using the slowest ranks counters included in newer versions of Darshan. It looks like the parser code inadvertently accounts for the amount of time spent doing metadata twice, rather than just once, in this estimation.

We should verify the estimate is being calculated properly and that the values being output by this mode are clearly described so this is more clear to the user.
