Commit Message

Fix libgpiod line ownership bug in GPIO functions (#134)

The libgpiod implementation had a critical resource management issue:
gpio_direction() acquired a line via gpiod_line_request but never
released it, causing gpio_write() and gpio_read() to fail when they
tried to re-request the same line.

Fix by caching line objects in a static array. gpio_direction()
releases and re-requests to change direction, while gpio_read()
and gpio_write() reuse the already-requested line directly.
gpio_unexport() now properly releases cached lines.

This fixes GPIO failures on Raspberry Pi with kernel 6.6+ when
built with libgpiod support.
