Fixing errors on Linkshell/Linkpearls/Pearlsacks

[lili-ffxi]

This change fixes two errors that happen when parsing Linkshells with certain combinations of characters that result in a bitpacked LS name that contains zeroed bytes in the middle.
First change fixes the nil error, second change detects the length of the name properly.

A better/more elegant/leaner way of doing it is welcome. This was the most basic way I could come up with.

If you're sure there is at least one non-null byte (which makes sense, I think? Considering it's only parsed in case of an LS name) you can do this:

localname_end=#strwhilestr:byte(name_end) ==0doname_end=name_end-1end

If you want to make sure it's at least 10 you can add and name_end > 10 to the loop's condition.

I famously forget that while and until exist, especially at 4am.

Done. I put the > 10 in, should never actually be needed but I thought it's maybe better safe than sorry.

They are usually worth forgetting.
