BoundCRS::identify(): improvements to discard CRS that aren't relevant (fixes #1801)

Fix for
```
projinfo --identify "+proj=utm +zone=48 +a=6377276.345 +b=6356075.41314024 +towgs84=198,881,317,0,0,0,0 +units=m +no_defs +type=crs"
```

to only return BoundCRS of EPSG:3148: 70 %

Previously it also returned EPSG:23948 and EPSG:24048 whose projected CRS-only
parts where likely matches, but those 2 CRSs don't have a +towgs84=198,881,317,0,0,0,0,
so discard them.
