v1.5.0-alpha hides parseCommandLine

To give users of my LS API client/server the same commandline interface they are used to from tsc, I have been using parseCommandLine, but quite recently, and sadly affecting v1.5.0-alpha, this has been marked @internal and is no longer available.

Could you please re-expose this? Ironically, as far as I can tell, the culprit seems to have been a patch that was meant to expose more functions:

    Expose readConfigFile and parseConfigFile

My users are getting impatient with me depending on the github version of TS, and now I can't offer them use the new npm alpha:-(
