Improve `ERR` trap (#58) - add `errtrace` so functions inherit the trap - report on `stderr`, not `stdout` (whoops) - report the correct file, not the script that may have `source`d it - use sometimes-clickable `file:line:` syntax - report which element(s) of a pipeline failed - report the exit code - include a stack trace
