Add LBP pallet to krievo to enable decentralised initial price discovery

[monsieurbulb]

It makes sense to concentrate basic tools + functionalities within krievo allowing a collective/network/token to bootstrap in a simple, intuitive but fully decentralised process.

Adding Basilisk's LBP pallet which is based on Balancers model will allow for price discovery.

Allow flexible parameters for communities to set the best method e.g. see Gitcoin LBP.

Would generate fees in dUSD for krievo/virto treasury.

Pool would be native token + dUSD.

Asset would then list on asset conversion pallet with dUSD pair.

Also check zero liquidity LBPs.

We will evaluate whether we should implement this as a pallet in Kreivo or propose it as an extension to the asset conversion pallet in Kusama AssetHub which seems the better thing to do but comes with a longer process of reviews and scrutiny.
