Modify SBNDOpHitFinder to allow for a channel-dependent threshold

[asanchezcastillo]

Description

This PR modifies SBNDOpHitFinder to allow for a channel dependent ADCThreshold. This changes is made to mee the needs presented at docdb-39495 . This is a temporary fix that runs the peak finding algorithm with the lowest ADCThreshold of the list and then only saves the OpHits that pass the ADCThreshold for each channel. Ideally, the peak finder algorithm should be run for each channel with and independent threshold, which is not possible with the current implementation of the algorithm in larana. This PR in larana implements the required changes to larana, but will require migrating sbndcode to larsoft v10.

As soon as the larana PR is merged and sbndcode migrated to larsoft v10 this modification can be reverted and updated to match the definitive implementation.
