Subject: [PATCH] Parse decimal building heights

The OpenMapTiles profile parsed height and building level tags with an explicit base argument to tonumber. Newer Lua runtimes reject decimal strings in that mode, so valid values such as height=18.5 and building:levels=3.5 fell back to the default one-floor render height while LuaJIT accepted them.

Parse these fields without an explicit base so decimal OSM values are handled consistently across Lua runtimes without changing integer handling or fallback behavior.
