MicroOCPP v1.2.0

New features (for OCPP 1.6 and 2.0.1), optimization of internal data structures and slight changes of the API.

PIO package: matth-x/[email protected]

Some of the internal changes also affect the API in MicroOcpp.h (e.g. ReadingContext has been refactored from a C++ enum class to a C-style enum). See the descriptions in the PRs for potentially breaking changes.

New features release, bug fixes and experimental OCPP 2.0.1 support.

PIO package: matth-x/[email protected]

The API in MicroOcpp.h / MicroOcpp_c.h is compatible with the v1.0 API. See the migration notes for a few important things to consider nevertheless: Migrating to v1.1

The experimental OCPP 2.0.1 implementation is disabled by default and won't be compiled into the firmware. See the README for a description on how to try it out.
