Adjustment for the removal of IncrementalEdit(offset:length:replacement:)

This initializer was only introduced very recently since `IncrementalEdit` stores the replacement bytes instead of just the replacement length. We are now changing `IncrementalEdit` store the range it’s replacing as `Range<AbsolutePosition>` instead of `ByteSourceRange`.
