Code Activity

- Use the new Crypto, TypeConversion and random() functionality added to the Arduino core, instead of the versions local to the mesh library.

Browse Source 
- Rearrange class variables to minimize storage padding.

- Add protected getters for EspnowMeshBackend and MeshBackendBase components.

- Partially update README.md
