Moves the separate repos for ICS23 proof tooling into `store/tools` I've set `github.com/confio/ics23/go` to version 0.7.0 in anticipation of https://github.com/confio/ics23/pull/61 being merged, as it's a dependency for SMT proofs, so this shouldn't be merged until that version exists. Closes: https://github.com/cosmos/cosmos-sdk/issues/10801 --- ### Author Checklist *All items are required.
