Update airdrop script and distribution

[Kouteki]

Description

When I tried to update the airdrop distribution from 75% to 70%, I realized there are a few gaps in the script that need to be closed in order to retrace the steps and verify that the distribution is correct.

Improvements

• consolidate/process_consolidate.go no longer requires the user to manually unpack the snapshot archive
• consolidate/process_consolidate.go now stores the output in genbalance.txt.gz
• Distribution updated from 75% to 70%

Steps to Reproduce

• Run consolidate/process_consolidate.go
• Run mkgenesis/makefile

If we believe the process_consolidated.go code, this looks good 💯

I also ran @aeddi's scripts to verify them, all good it seems:

Importing balance file: ../mkgenesis/balances.txt.gz
Importing balance file: ../mkgenesis/non-airdrop.txt
Importing balance file: ../consolidate/genbalance.txt.gz
Adding non-airdrop to consolidate balance file
Comparing ../mkgenesis/balances.txt.gz with ../consolidate/genbalance.txt.gz
Balance files match.
