Add TANTOF405

[VitroidFPV]

Accompanying #1028

Summary by CodeRabbit

• New Features
  • Added support for the TANTOF405 flight controller board with complete hardware configuration: onboard accelerometer and gyroscope options, barometer, on-screen display and flash-based logging, beeper and LEDs, motor and servo outputs, USB and multiple serial/I2C/SPI interfaces, and configurable I/O pins.
  • Ship defaults for telemetry, DSHOT behavior, current/voltage metering and sensible runtime parameters.

Walkthrough

Adds a new Betaflight target configuration header for the TANTOF405 (STM32F405): hardware IDs, sensor/peripheral feature flags, detailed I/O and timer mappings, peripheral instances, DMA/serial settings, and default runtime parameters including SYSTEM_HSE_MHZ and meter/DSHOT defaults.

Changes

Cohort / File(s)	Summary
TANTOF405 Board Configuration configs/TANTOF405/config.h	New board config header. Declares MCU/board/manufacturer macros, enables sensors (accel/gyro/baro), flash and OSD, maps motors/servos/beeper/LEDs/UART/I2C/SPI/ADC/USB pins, defines timer pin mapping, DMA/serial/magnetometer/barometer instances, sets SYSTEM_HSE_MHZ and other default runtime parameters (blackbox, DSHOT, meters). Review timers, DMA options, SPI/I2C instances, and HSE value closely.

Check name	Status	Explanation	Resolution
Description check	⚠️ Warning	The pull request description is severely incomplete, containing only a reference to issue #1028 without addressing any of the mandatory template requirements for new flight controller submissions.	Complete the description by filling out the mandatory checklist items (schematics review, hardware testing, guideline compliance, connector standards, flight testing, issues resolution) and provide details about the TANTOF405 hardware and design.
Title check	❓ Inconclusive	The title 'Add TANTOF405' is vague and generic, using non-descriptive language that doesn't convey meaningful information about what TANTOF405 is or why it's being added.	Improve the title to be more descriptive, e.g., 'Add TANTOF405 Betaflight flight controller configuration' or similar to clarify the board/target being added.

to be clear the lsm16 is not recommended we have been unable to get it working to a level that we would endorse it. and do these guys want a t1 target if so they need to email us
