cargo-nextest 0.9.37

Added

• Support for a negative value for --test-threads/-j, matching support in recent versions of
  Cargo. A value of -1 means the number of logical CPUs minus 1, and so on. Thanks Onigbinde
  Oluwamuyiwa Elijah for your first contribution!
• Add a note to the help text for --test-threads indicating that its default value is obtained
  from the profile. Thanks jiangying for your first contribution!

Changed

• Internal dependency target-spec bumped to 1.2.0 -- this means that newer versions of the windows
  crate are now supported.
• MSRV updated to Rust 1.62.
