feat(jstzd): add bootstrap contracts to ProtocolParameterBuilder

[huancheng-trili]

Context

Part of JSTZ-149.

JSTZ-149

Description

Adds bootstrap contracts to the base protocol parameter set.

A BootstrapContract instance has 3 fields:

pub struct BootstrapContract {
    script: serde_json::Value,
    amount_tez: u64,
    hash: Option<tezos_crypto_rs::hash::ContractKt1Hash>,
}

script is the contract code in micheline JSON format. hash is the hash of this contract to be deployed. Note that it's optional because the node will just generate one if it's not given, but it can actually be set to any valid contract hash, which might be handy when we need to know the address of a contract in advance.

Manually testing the PR

• Generated one parameter file with the sample contract code attached and tested the file in a sandbox.
• Unit test: add new test cases
• Integration test: waiting for other octez client implementation
