Execute the embedded parser at least once with another parser as separator, then produce a list of values. Separator can be trailing.
sepEndBy1(char(","), digit())("1,2").output; // ==> ["1", "2"]
sepEndBy1(char(","), digit())("1,2,").output; // ==> ["1", "2"]
sepEndBy1(char(","), digit())("1,2,").input === "";
sepEndBy1(char(","), digit())("").ok === false;
