nrUCIDecode may have bad performance in 1 or 2 bit case

In nrUCIDecode, we see function use below code block:

if A==1

N = Qm;

else

N = 3*Qm;

end

% Rate recovery

typeIn = class(uciLLRs);

E = length(uciLLRs);

rec = zeros(N,1,typeIn);

if E>=N

% Pick the first N values, no averaging

rec = uciLLRs(1:N,1);

else

rec(1:E) = uciLLRs;

end

where A is the UCI bit number, so let's use 1 bit UCI and QPSK modulation as exampe: in such case, N = Qm = 2, and rec = uciLLRs(1:N,1); --> it means function will only use first two bit for further process even when total LLR softbit number is quite large(e.g. 160 bits), which will lead to performance degradation.
