Description

Implementing Encode and Decode for Poplar1AggregationParam is suggesting that Lsb0 may have not been a good choice for bit ordering in various intermediate storage data types. We may want to revisit this in the future to simplify things.

Research direction

Start by examining the Encode and Decode implementations for Poplar1AggregationParam and the intermediate storage data types that use bitvec::prelude::Lsb0. Determine whether the bit ordering choice complicates those implementations and identify the affected uses. Done means reaching and documenting a decision on whether revisiting Lsb0 would simplify the design.
