Fix a bug for Ols DPB initialization

See merge request jvet/VVCSoftware_VTM!1701

At the encoder there are long parameters like "--QP=32" and short parameters like "-q 32"

For layer parameters -lx (with x being the layer index) the encoder always assumes that
-lx is followed by two parameters, which is only true for short type parameters.

This checks for "--" in the first parameter following -lx and only reads a second parameter,
if "--" is not found at the beginning.
