Tile path 0x0021 has only one tile in it and the emitted FastJ tile from the "pasta" tool does not correctly report that the emitted tile is a "startTile". The "endTile" flag is properly set and there is correctly no "startTag" (or a zero length "startTag").

I believe the culprit is in the pasta_fastj.go file. There's a condition when it's processing the end tile to make sure it fills in the beginning tag with the appropriate value if it's able. Instead of doing nothing in the case of not being able to fill the beginning tag, it should set the "start_tile_flag" to true so the appropriate field can be populated in the FastJ header.

It's a special case of when the tile path is only one tile long so the error is not critical but it would be nice to fix.
