Fix for the h5gLDPCEncode from 5G Library for LTE System Toolbox (version 1.2).
The way the lifting size was chosen for the encoder in h5gLDPCEncode.m doesn't match the 3GPP specs and doesn't match the way the lifting size is chosen on the decoder size.
It may also lead to errors for some inputs size because the lifting size Zc is simply chosen as size(in, 1)/22 for basegraph 1 for instance.
For this reason LDPC encoding -> rate matching -> rate recovery -> decoding doesn't work even at infinite SNR. This fixes this issue and was uploaded here so the team working on the 5G library could see it
