 Changes from that package:
 * Uses build tags to eliminate all overhead when not enabled
-* Tests now pass race checker and improves code coverage
-* Improved performance when using go 1.18+
-* Uses significantly less memory (details in https://github.com/linkdata/deadlock/issues/2)
+* Tests pass race checker and has full code coverage
+* Guards against github.com/petermattis/goid not supporting the current Go version
 * Diagnostic output matches `-race` style and uses `runtime.CallersFrames` to get correct line numbers
 * Adds `deadlock.Enabled` and `deadlock.Debug` constants
 * Adds `Try(R)Lock()` when using go 1.18+
 * Drops the dummy implementations for types other than `Mutex` and `RWMutex`
