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.

Proofs Tendermint
This is an adapter library to convert the SimpleProof from
tendermint/crypto/merkle
into the standard confio/proofs format.
As non-existence proofs depend on ordered keys, and all proofs require the key-value pair
to be encoded in a predictable format in the leaves, we will only support proofs generated
from SimpleProofsFromMap, which handles the key-value pairs for leafs in a standard format.
Library usage
It exposes a top-level function func ConvertSimpleProof(p *merkle.SimpleProof, key, value []byte) (*proofs.ExistenceProof, error)
that can convert from merkle.SimpleProof with the KVPair encoding for leafs, into confio/proof protobuf objects.
It currently only works for existence proofs. We plan to soon support non-existence proofs.
CLI usage
We also expose a simple script to generate test data for the confio proofs package.
make testgen
Will output some json data, from a randomly generated merkle tree each time.

"root" is the hex-encoded root hash of the merkle tree
"existence" is the hex-encoding of the protobuf binary encoding of a proofs.ExistenceProof object. This contains a (key, value) pair,
along with all steps to reach the root hash. This provides a non-trivial test case, to ensure client in multiple languages can verify the
protobuf proofs we generate from the iavl tree
