Claude b85c98abb4 [tcal6416] Add support for TCAL6416 I2C I/O expander

Implements support for the TI TCAL6416 16-bit I2C I/O expander with the following features:
- 16 GPIO pins (2 banks of 8)
- Bidirectional I/O with configurable input/output modes
- Support for inverted pins
- Compatible with ESP32, ESP8266, and RP2040 platforms
- I2C interface with configurable address (default: 0x20)

The TCAL6416 provides higher current latched outputs suitable for directly
driving LEDs or keypads. It operates at voltages from 1.08V to 3.6V and
supports I2C speeds up to 1MHz.
