Update memo format and make memo updatable

[yoomee1313]

This PR updates memo format of the kip-103 and kip-160 and adds enabling editing memo section in kip-160.

• kip-103: revise memo format of a Info-log to match with the contract memo format
• kip-160: add new memo format. The reason of introducing new memo format is to get the additional balance data to calculate burnt amount directly.
• kip-160: added pendingMemo stroage and setPendingMemo method. finalizeContract doesn't accept memo string anymore.

@yoomee1313 I think this issue in here: Maybe we need to use the circleCI

@Sotatek-TinnNguyen I(yoomee1313) created this PR(#6) and check-link github action is passed.
I think it's related to this setting: https://docs.github.com/en/actions/managing-workflow-runs/approving-workflow-runs-from-public-forks#about-workflow-runs-from-public-forks
Can the change of this setting solve the problem..??

[Sotatek-TinnNguyen]

the github action works fine with PR inside repo but can not work with PR from fork repo @yoomee1313

[yoomee1313]

I'll merge this PR since check I have checked that check links actually works.
