Rui Wang Nov. 25, 2025, 12:08 a.m. UTC
Load tuning flags and gain levels on top of the single-config helper.
The parseConfig() function wraps parseSingleConfig() to load the base
configuration, then parses optional enable/devmode flags and any
exposure index -banded overrides.

Replace the inline parsing in init() with a call to parseConfig(). This
simplifies init() and allows the parsing logic to be reused. The refactor
also adds logging of the parsed base tuning and preserves the base config
for manual mode restoration.

Rework domain filter, NLL, gain, and strength parsing into a
parseSingleConfig() helper. This extracts the parsing logic so it can be
reused for both the base tuning and per-exposure-gain-level configuration blocks.

The init method now:
- Calls parseConfig() to load tuning data
- Logs the parsed base configuration
- Caches base config for manual mode restore
- exposure levels are sorted by exposure index threshold for efficient band selection
at runtime.
