Change file:reads to be *a instead of a*

This resolved an issue I had setting up tilekiln. I'm not a lua expert, but GPT claimed this was incorrect and changing it to match what it told me fixed my issue:

❯ osm2pgsql --output flex --style shortbread.lua -d spirit ~/osm/north-america-latest.osm.pbf

After the change:

Looking at the Lua documentation it seems the syntax for the read command was changed from *a in Lua version 5.1 and 5.2 to just a in version 5.3 and 5.4. Those versions seems to ignore the * so everything worked for them. I guess you have version 5.1 or 5.2. Thanks for the fix.

Weirdly, I actually had lua 5.4.7 and that was the one causing me issues! Thanks for merging!
