only use first 255 characters of source location
When a Lua script was loaded through loadstring, dbg.source is the whole source code; this not only causes a lot of unnecessary data to be sent, it can even crash Tracy if the source string is larger than 64 KB. Therefore, use the short version which is never more than 255 characters.
