Add address support in pzem-004t v1

**Describe the problem you have/What new integration you would like**
Hello. I have several modules pzem-004 v1. I wanted to assemble energy meters for 3 phases from them. But I encountered an unexpected problem. The pzem004t platform does not support either address selection or the ability to set it. V3 modules have this opportunity, but purchasing them entails large expenses and I would like to avoid this. Please add address support for modules v1.

**Please describe your use case for this integration and alternatives you've tried:**

**Additional context**

The request names the pzem004t platform but provides no source files, tests, or entry points. Start by locating that platform and researching how address selection works on PZEM-004T v1 modules; done means multiple v1 modules can be assigned or selected by address for a three-phase setup.
