tidal-listener: Code highlight message structure typo

[ndr-brt]

On the wiki it's reported that:
< /code/highlight <duration> <cycle position> <row> <col> <row> <col>
but the reality is:
< /code/highlight <duration> <cycle position> <col> <row> <col> <row>
In addition, row numbers start from 1 not from 0 as column numbers

We should move the tidal-listener wiki here too? Or document everything into a markdown in the repository?

I don't mind really.. Maybe in the repository is better?
We can unarchive the tidal-listener repo to edit in redirections once it's done.
