PR summary
So in 0.13.4 (yanked) tarpaulin actually started passing --cfg=tarpaulin so users could do #[cfg_attr(tarpaulin, ignore)] to ignore certain tests in coverage and also conditionally include/exclude code in coverage. This had the unintended result of breaking the recommended skip attr.
Because of that 0.13.4 was yanked and later on a 0.14.0 version released which still did --cfg=tarpaulin but also --cfg=tarpaulin_include so that code could now be skipped but still included if you did #[cfg(not(tarpaulin_include))]. There's also an unstable #[tarpaulin::skip] tool attribute for those using nightly.
This PR changes time to use the new attributes as a user of time and tarpaulin found this broke their coverage CI.

testing/benchmarking notes
I struggled to get holochain building and running coverage on it. Still working on that but it shouldn't functionally impact any code just driving the tarpaulin source analysis and exclusion functionality.
