periodogram.m: Overhaul function (bug #39279, bug #42859).
* contributors.in: Add Drew Abbot to list of contributors.
* periodogram.m: Rewrite documentation. Simplify input parsing of arguments.
Accept both row and column inputs for X. Correct onesided computation
when NFFT is odd. Add an error message about unrecognized range specification
"centered". Add input validation tests.
