This commit changes the BSUP version number from 0 to 1 and expands the version number bits from 0 to 7. There is currently no backward compatibility with version 0 and instead an error will be reported when trying to read old BSUP files.

| - Upgrade to `github.com/apache/arrow-go/v18@v18.5.1` (#6625) | ||
| - Type fusion now ensures fused types never contain unions, have at most one instance of each kind of non-union complex type, and have at most one type with a given type ID (#6651) | ||
| - Type decoration for self-describing error values in SUP are now omitted (#6656) | ||
| - By default, `super` now reads the first 1000 values when reading from an input file to compute a fused type, and the `-samplesize` flag can be used to adjust this (#6667) |
