Function concordium_contracts_common::deserial_map_no_length

pub fn deserial_map_no_length<R: Read, K: Deserial + Ord + Copy, V: Deserial>(
    source: &mut R, 
    len: usize
) -> ParseResult<BTreeMap<K, V>>

Read a BTreeMap as a list of key-value pairs given some length. NB: This ensures there are no duplicates, hence the specialized type. Moreover this will only succeed if keys are listed in order.
