function update_linear_gaussian_gaussian(x:Real, a:Real, μ:Real, λ:Real, c:Real, l:Real) -> (Real, Real)

Update the parameters of a Gaussian distribution with a Gaussian likelihood and scaling.

• x: The variate.
• a: Scale.
• μ: Prior mean.
• λ: Prior precision.
• c: Offset.
• l: Likelihood precision.

Returns: the posterior hyperparameters μ' and λ'.
