- Delete unused declaration of `g_is_component_initialized`.
- Replace the following constants with approprite config options:
+ `relay_chn_count` > `CONFIG_RELAY_CHN_COUNT`
+ `opposite_inerta_ms` > `CONFIG_RELAY_CHN_OPPOSITE_INERTIA_MS`
- Replace the definition of the `test_delay_margin_ms` constant with `#define TEST_DELAY_MARGIN_MS 50` for preprocessor calculations.
- Removed unnecessary calls to relay_chn_create and g_is_component_initialized in multiple test cases across test_relay_chn_core_single.c, test_relay_chn_listener_multi.c, and test_relay_chn_listener_single.c.
- Introduced new test files for NVS functionality: test_relay_chn_nvs_multi.c and test_relay_chn_nvs_single.c, covering initialization, direction setting, invalid parameters, and erase operations.
- Updated partition table configuration to support NVS storage, including the addition of a new partition file part_nvs.csv.
- Adjusted sdkconfig files to enable NVS support and configure custom partition settings for relay channels.
- Created `test_relay_chn_tilt_multi.c` and `test_relay_chn_tilt_single.c` to implement comprehensive tests for the tilt functionality of relay channels, covering various scenarios including transitions between states and sensitivity settings.
- Introduced a new partition table in `partitionTable.csv` for proper memory management.
- Updated `sdkconfig` to set the relay channel count to 1 for single channel testing and adjusted related configurations.
- Added default configuration file `sdkconfig.defaults.single` for streamlined testing setup.
