Nested array, mapping, etc.

for kinds of contracts

the owner support tee only, variable owner will be useful in MPT, you can see the example below.

pragma cloak >=0.2.0;

contract Sum {
    uint256@tee res;
    final address p1 = 0x58c453B66f57a37211881783c628B9Bc0FDe5605;
    final address p2 = 0x13d202872aEcB7adCEF304A4689deacb6E939B79;

    function sum(uint256@p1 _a, uint256@p2 _b) public {
        res = _a + _b;
    }
}

For a transaction, we can read the history and status of the transaction through API

see #6.

evm will select uint256 by default when processing uint type data, resulting in inaccurate function entry addresses before and after encoding.

for example，
The current encoding function entry method is

[bytes4] sha3(function(uint))

Should be modified to

[bytes4] sha3(function(uint256))

If the user account is not initialized before enabling, it will cause errors in subsequent operations such as reading the nonce

merge #8, build code can find a error is follow:

undefined reference to `fmt::v7::format_error::~format_error()'

support synchronization(sync to public chains) of mapping owner

Research the Proof of Publication solutions of a system which combines TEE and Blockchain

Reason: File path in json changed because of update of solc version 0.8.10
Solution: Need to use pysolcx lib to adapt to different version of solc

some util functions (e.g. run_in_evm) has been implemented in evm_for_ccf.cpp, which will cause some coding problems, specially in reusability aspect, so we need to refactor that codes.
