Overview

Currently, zeros are run length encoded using the format <length_u8>00. @Vectorized brought up that in situations where zero bytes are non-repeating, it may be more efficient to encode them as <length_u8 - 1>00 to save on non-zero calldata byte costs.

Action item

Profile this optimization to determine whether it saves gas on average. If so, change the encoding scheme to further optimize calldata costs per @Vectorized's suggestion.
