Adds CLOCK_90 and the nixie595.ino driver: two 74HC595s on hardware SPI (GPIO13/14, latch GPIO15), multiplexed from an IRAM-only timer1 ISR. Neon dots on P1; P2 is the decimal-point line on this board. Also: - NeoPixel on any ESP8266 pin via bit-bang (GPIO12), and take the pin back after SPI.begin() claimed it as MISO - ArduinoOTA (USE_ARDUINO_OTA), with an OTA upload env in platformio.ini - DST: EU end date (last Sunday of October) instead of the first Sunday of November, and recompute the time from the rules when DST is toggled instead of shifting it by 1 h - forward declarations so PlatformIO's .ino conversion compiles - FIRMWARE_SERVER can be overridden; empty for CLOCK_90 Verified on the clock: tubes, order, dots, LEDs, LDR, NTP time with DST.
