dump chunks

go test -v ./pkg/storageincentives/ -run TestSocMine -count 1 > socs.txt

to generate uploads using the input

cat socs.txt | tail 19 | head 16 | perl -pne 's/([a-f0-9]+)\t([a-f0-9]+)\t([a-f0-9]+)\t([a-f0-9]+)/echo -n $4 | xxd -r -p | curl -X POST \"http:\/\/localhost:1633\/soc\/$1\/$2?sig=$3\" -H \"accept: application\/json, text\/plain, \/\" -H \"content-type: application\/octet-stream\" -H \"swarm-postage-batch-id: 14b26beca257e763609143c6b04c2c487f01a051798c535c2f542ce75a97c05f\" --data-binary \@-/'

it also serves as a sanity check showing the number of chunks it needed to find. 16 below the max value
