Instead of waiting for a good time to switch the `Map` implementation, I've decided to just offer two implementations: one for Go versions before 1.18, and one for 1.18 and onwards. This is achieved using build tags in the source files. This is obviously a breaking change for consumers of this library that use Go 1.18 and onwards. See #88
