Thanks so much for using the library and the PR.

The conversion of all xyz.cpp to xyz-Impl.h is intentional to

1. Let #define in sketch (for example debug, important definitions, etc.) valid anytime when you compile.
2. You don't have to modify the xyz.cpp just to modify certain options set by #define

You can try to see the feature and why.

Depending on your code, you can have linker complaint sometimes. The solution can be either

1. Convert you all your code from abc.cpp to abc-Impl.h so that all files are compiled at the same time, not pre-compiled as in the case of abc.cpp.

See the similar problem and solution in Issue 3 of WebSockets2_Generic: multiple definition of `websockets2_generic::WebsocketsServer::~WebsocketsServer()' in websocket2_generic library

2. Check you code to include the file correctly and only when necessary. This is not possible in all cases.

3. Convert the library code from xyz-Impl.h back to xyz.cpp as you did.

I won't modify the library back as your PR, but will put a note in README so that anybody having the similar issue can know how to deal.

Certainly I will add a note for your contribution.
