update_beta_isotonic

<code>update_beta_isotonic</code> updates beta for L2E isotonic regression using PG

An implementation of a computational framework for performing robust structured regression with the L2 criterion
from Chi and Chi (2021+). Improvements using the majorization-minimization (MM) principle from Liu, Chi, and
Lange (2022+) added in Version 2.0.
