Expose getDependencies() for SubscriberPackageVersion class

[ClayChipps]

Currently, the @salesforce/packaging SubscriberPackageVersion class does not expose a public getter function to retrieve the dependencies.

I am proposing adding a new getter function getDependencies() that will allow a clean api to get the package dependencies. (Similar to getRemoteSiteSettings()).

Hi Clay! I see no reason to not add this. Would you like to handle the PR and I'll make sure it doesn't get held up?

Function will be added in the release candidate version of the CLI on January 10th, or available in tomorrow's nightly release.
