Layer<E, Service> class
A Layer can be used to construct a service.
It will only be built once per ZIO execution, or it can be provided to a Runtime using Runtime.provideLayer.
If it is provided to a Runtime, it will be built once per Runtime - being reused for all ZIO executions.
It can be accessed using access or accessWith. Or by calling ZIO.layer.
You can also replace a Layer using Layer.replace.
