running Auto_ViML with hyper_param='HO' throws an exception.

Im testing Auto_ViML with hyperopt on the titanic dataset, running it like this:

        train, target, test,
        verbose=0,
        hyper_param='HO',
)```

This throws the following exception:

specifying the evaluation metric doesnt fix the issue.

Im using `autoviml==0.1.651`.

I haven't completed the HO hyper parameter tuning yet -> until then I suggest you use 'RS' or 'GS' for hyper_param parameter. sorry. Both work well.

got it, would be nice to mention that in the docs.

@manugarri please submit a PR for the readme

Done, I submitted a PR for the docstring (optimization methods are not mentioned in the readme) #13
