* Add macros header with more usable Arduino version defines * Change Arduino version checking to use our version defines * Add missing ESP8266 check * Rename Arduino version macro to ARDUINO_VERSION_CODE * Upgrade clang-tidy to use Arduino 3 * Fix clang-tidy warnings * Upgrade NeoPixelBus to upstream 2.6.7 * Use Arduino-version-appropriate API to set redirect flags * Remove now unnecessary CLANG_TIDY ifdefs * Add preprocessor hackery to avoid including pgmspace.h * Bump base image to 4.1.1 and update lint * Fix nfctag * Fix make_unique ambiguous * Fix ignore name * Fix ambiguous v2 * Remove unused begin * Cast time_t to prevent issues on platforms where time_t is 32bit Co-authored-by: Otto winter <otto@otto-winter.com>
