fix: simplify data structure before release (#9968)

Browse Source 
- additionally upgrade to msgp@v1.1.2
- change StatModTime,StatSize fields as
  simple Size/ModTime
- reduce 50000 entries per List batch to 10000
  as client needs to wait too long to see the
  first batch some times which is not desired
  and it is worth we write the data as soon
  as we have it.
