Pull request overview
This PR adds configuration options to selectively reject either the inner or outer ring channels of the FT0A and FT0C detectors in long-range dihadron correlation analysis. This functionality allows for systematic studies of detector response and helps in understanding contributions from different detector regions.
Key Changes:
- Added four new boolean configuration options to enable rejection of inner/outer rings for FT0A and FT0C detectors independently
- Introduced a DetectorChannels enum defining the channel ID ranges for inner and outer rings of both detectors
- Implemented rejection logic in the getChannel function by setting amplitude to 0 for channels in the rejected rings

The DetectorChannels enum lacks documentation explaining the meaning of these channel ranges. Consider adding a comment block above the enum describing the FT0 detector geometry and how these channel ranges correspond to the inner and outer rings of the FT0A and FT0C detectors.

The configuration allows enabling both inner and outer ring rejection simultaneously (e.g., both cfgRejectFT0AInside and cfgRejectFT0AOutside can be true), which would reject all channels of a detector. Consider adding validation logic to prevent this configuration, or document that this is an intentional feature if the use case exists.
