chore: master document containing a log of the TODO comments found in the project files

[MoonBoi9001]

While reviewing the OZ audit N-04 I found advice to document TODO comments inside our project issues backlog.

I found the following TODO's at commit 4387c6cdc7cf437e75b46d3af3f1d88aa1fdb925

The following TODO's are on .sol files.
