Function rgb20::transfer

pub fn transfer(
    asset: &Asset, 
    inputs: BTreeSet<OutPoint>, 
    payment: BTreeMap<SealEndpoint, AtomicValue>, 
    change: BTreeMap<SealDefinition, AtomicValue>
) -> Result<Transition, TransferError>

Function creates a fungible asset-specific state transition (i.e. RGB-20 schema-based) given an asset information, inputs and desired outputs
