Title: table.write list valid output formats?

(feature request) Could we change the error message for `table.write` failures to include info about valid output formats? Currently, the message is `Exception: Format could not be identified`, and it wasn't easy to track down the valid writers (but I did, they're here: `astropy.table.io_registry._writers`). I can implement this if it seems reasonable.
