Update the variational density for the kth mode when assuming a diagonal Kronecker structured covariance matrix.

1 2	tupdate_kron_modek(Y, ex_list, ex2_list, esig_list, k, mixcompdist = "normal", which_na = NULL, nullweight = 10)

`Y`	An array of numerics. The data array.
`ex_list`	A list of vectors of numerics. The expected values of the components of each mode.
`ex2_list`	A list of of vectors of positive numerics. The variational second moments of the components.
`esig_list`	A list of vectors of positive numerics. The expected variances.
`k`	A positive integer. The current mode to update.
`mixcompdist`	The mixing distribution to assume. Defaults to normal. Options are those available in the `ashr` package.
`which_na`	Either NULL (when complete data) or an array of logicals the same dimension as `Y`, indicating if the observation is missing (`TRUE`) or observed (`FALSE`).
`nullweight`	A numeric greater than or equal to 1. The penalty term on the probability of a component being zero.
