Describe changes:

• Random Reward Function:
  Implements a mechanism to deliver rewards based on random scheduling, adding variability to the experimental paradigm.

• Dual Lick Spouts Support:
  Allows configuration of two separate lick spouts, each with its own reward volume setting.

• Configurable Inter-Reward Interval:
  Supports defining inter-reward intervals using either an exponential or even distribution.

• Reward Collection Check:
  When enabled, ensures that the next trial will only begin once the current reward has been collected, preventing premature trial progression.

• Data Save:
  Data including parameters used in each trial, reward timestamps, and metadata will be saved.
