`\formatname` and `tex.formatname` are empty

[gucci-on-fleek]

\formatname and tex.formatname are always empty. Example:

\message{\formatname}
\directlua{print(tex.formatname)}
\end

According to the LuaMetaTeX manual, both of these commands have been removed from the engine, but that doesn't actually seem to be the case since \formatname is defined but empty and tex.formatname is an empty string instead of nil.

Both \formatname and tex.formatname work in ConTeXt LMTX, although I couldn't figure out how they're set.

It's a question of engine versions. formatname works again in the updated LuaMetaTeX version, but that version breaks accent placement in LaTeX, so updating requires a bit more thought.

Hopefully fixed, but requires an updated engine (so rerunning the installer).

Yep, it's fixed. Thanks!
