Add ready to use configuration for Olimex ESP32-POE-ISO Rev. L with CMT2300A

[MPW1412]

Hello,

maybe this is trivial to experts here, but as beginners some friends and I struggled quite a bit to find an example for this combination of Olimex ESP32-POE-ISO with CMT2300A.

Here's my working solution with some extra comments.

I think it would benefit others if it were available within the official project.

Best,
Matthias

Could you maybe just add this profile in the file https://github.com/tbnobody/OpenDTU/blob/master/docs/DeviceProfiles/olimex_esp32_poe.json which already contains several profiles for the Olimex POE module?

Hm, I could do that. I have to say though that as a beginner, I was quite confused by all the configurations in one file. Wouldn't it be easier to have one file dedicated to your setup? There are multiple Olimex configuration files already anyway.
