Parse error with immutable property

[H34D]

pragma solidity 0.6.12;

import "@openzeppelin/contracts/token/ERC20/ERC20.sol";

contract MyContract {
    // token
    ERC20 public immutable token = new ERC20("test", "test");
}

leads to

$solgraph ./contracts/MyContract.sol

The parser needs to be updated from solidity-parser-sc to solidity-parser-antlr or another parser that supports the latest solc. I don't have the time unfortunately but I would be happy to support a PR from anyone who is interested in contributing.

Fixed in v1.0.0. Special thanks to @yellowBirdy.
