Issue DM-5323: estimateBackground should not make a deep copy of the exposure
Implement RFC-155: change {{estimateBackground}} as follows: - Always subtract the background - Modify the exposure in place - Replace {{estimateBackground}} with the run method of a new task {{SubtractBackgroundTask}} - Replace {{getBackground}} (which fits a background) with {{SubtractBackgroundTask.fitBackground}}
