Implement Enable Automatic Punctuation

[eric-kruger]

Hi Mark,

Would it also be possible to enable Automatic Punctuation in future releases of googleLanguageR?

Thanks,
Eric

Yep this too. I look to include the beta features on the dev version on GitHub, then once they are out of beta move it into the CRAN version.

I came to request this also. Mark, truly awesome packages -- thank you very, very much for sharing. I'm going to look through your code a bit more, hopefully I can submit some useful pull requests to help development.

See #47 for discussion

The example in this case would be:

## Use a custom configuration
my_config <- list(enableAutomaticPunctuation = TRUE)

# languageCode is required, so will be added if not in your custom config
gl_speech(my_audio, languageCode = "en-US", customConfig = my_config)
