Consistently use RawBank::View as input to algorithms instead of RawEvent

• remove use of concat_alternatives
• make lifetime-management shared_ptr in event store 'write only'
• remove 'stream' argument in make_ODIN -- use whatever stream is defined for make_raw (i.e. make_raw_banks). This avoids the need for spurious, redundant bind statements downstream.

required for Rec!3351 (merged), Alignment!360 (merged) and Moore!2166 (merged)
