conf/parse_pem.go文件中建议添加外部访问函数

有时需要外部直接访问`parsePKCS8ECPrivateKey`和`parsePKIXPublicKey`，后续可以添加两个`ParsePKCS8ECPrivateKey`和`ParsePKIXPublicKey`函数供外部直接访问吗

使用前端按文件夹导出的abi和bin文件部署合约错误

5

webase 1.5.4 fisco-bcos 2.8.0 solidity 0.6.10 场景：A、B两个合约，A合约引用B合约，在A合约的构造函数中引用了B合约的public函数，且修改了B合约的状态变量 这两个合约在WeBASE中都可以正确部署并运行 -------------------------------------- 出现错误的操作 按文件夹导出abi、bin文件，使用go sdk中的abigen工具生成go文件 使用go代码部署B合约，正确返回 使用go代码部署A合约，错误，状态码0x16，revert ----------------------------------------- 使用以下方法避免了该错误 导出sol文件后，使用solc重新编译A、B合约的 abi文件和bin文件 再次使用abigen生成go文件，使用go代码部署合约，A、B均成功部署 --------------------------------------- 因此对于有引用的合约，使用前端导出abi文件和bin文件生成go文件并部署合约时会有报错

将代码粘贴到IDE中，有时会触发一个bug，不能清空代码文件

2

 删除完全部代码后又会复原，但可以更新保存，此时删除全部代码复原后是保存后的代码，前端console没有error日志 还有一个问题，以后会不会实现将代码保存在localstorage中，就像remix一样
