options { initial: 1000 } is rejected with 'bad initial passed'

from connection_opps.cpp

if (!enc.parseOption<&lcb_cmdcounter_initial>(info[4])) {key: my-counter 1

{"initial":1000,"timeout":5000}

(err, res) =>

{         console.log("res: " + JSON.stringify(res));       }

Error: bad initial passed

In discussion with Brett Lawson, he pointed out that the same parseOption is used for Cas and options.initial.  And that I should rename the existing parseOption( .. uint64)   to parseCasOption() and use that on Cas.  And create a new parseOption(.. uint64) for other cases (like initial.options).  I tried that and it works.
