fix: Make sure table name handling is done by the crate instead of clap

[clflushopt]

To allow supporting actual short hand we have to ensure that we use a custom TypedValueParser that is able to parse the refs correctly and align every abbrv with its long name and corresponding enum, one downside is that we lose some of the auto-derived nice things from clap like the list of options in the --help message due to a conflict from deriving ValueEnum vs implementing FromStr ourselves which is necessary to allow both abbrvs and long names.

I don't like this code because it's a lot of gymnastics for supporting command flags (I feel like clap is very much too powerful for our needs but maybe I am used to Go's stdlib provided argument handler).

There's also some non-trivial complexity in the implementation (side effect of how clap does things).

Closes #91

Thanks @clflushopt !

Thanks @clflushopt -- I didn't quite follow if you thought this PR was to complicated or if the clap implementation was too complicated. Is there anything you think we should be changing anything about this complexity?

@alamb The PR itself is not complicated, my comment was specifically about the ergonomics of clap but I guess it's powerful for a reason (less stuff for us to implement !).
