Description
Currently the byte-view array colocates offset with prefix. An alternative design is to separate them and use linear regression to compress the offset array.
I think @JP-Reddy is working on this

Research direction
Start by locating the byte-view array implementation and reading how it currently colocates offsets with the prefix. Compare that representation with the proposed separated offset array and linear-regression compression, including how success would be measured. Confirm whether @JP-Reddy's work has already addressed this before starting.
