feat: Compatibility between the voteweighted package and ICS consumer keeper

[Eric-Warehime]

Adds compat types so that ICS chains can use slinky.

It uses validator power instead of bonded tokens in the stake-weighted median computation.

It uses the most recent version of ics v5.0.0-alpha1.

Seems nice! Two requests:

• there is no way to create CCVConsumerCompatKeeper now, because ccvKeeper is a private field. Can you add a constructor to it please?
• can you also implement another ValidatorStore as well for CCVConsumerCompatKeeper? (it's used in another place)

type ValidatorStore interface {
	GetPubKeyByConsAddr(context.Context, sdk.ConsAddress) (cmtprotocrypto.PublicKey, error)
}

I implemented it like this (seems to be working):

func (c ConsumerValidatorStore) GetPubKeyByConsAddr(ctx context.Context, consAddr sdk.ConsAddress) (cmtprotocrypto.PublicKey, error) {
	sdkCtx := sdk.UnwrapSDKContext(ctx)
	val, found := c.k.GetCCValidator(sdkCtx, consAddr)
	if !found {
		// TODO
		return cmtprotocrypto.PublicKey{}, fmt.Errorf("not found CCValidator for address = TODO: ")
	}

	consPubKey, err := val.ConsPubKey()
	if err != nil {
		// TODO
		return cmtprotocrypto.PublicKey{}, fmt.Errorf("TODO")
	}
	tmPubKey, err := cryptocodec.ToCmtProtoPublicKey(consPubKey)
	if err != nil {
		// TODO
		return cmtprotocrypto.PublicKey{}, err
	}

	return tmPubKey, nil
}

how about using sdkCtx := sdk.UnwrapSDKContext(ctx)?
