INLA version 23.08.18

[Håvard Rue]

We're out with a new testing version for R-4.3, hopefully with a better
optimiser for hard models (read flat posteriors), but more importantly
that the 'fmesher' program is now in a separate R-package, 'fmesher'.
This program generate meshes for the spde-models. Here is info in the
NEWS

Depend on the new fmesher package. By default, the new methods are
used silently instead of the old fmesher standalone binary, and are
meant to produce the same meshes etc as before. During a transition
period, one can switch between the two code bases, as well as turn on
informative deprecation warnings that point to which fmesher R
function replaces the existing ones. See
https://inlabru-org.github.io/fmesher/articles/inla_conversion.html
for more details.



The fmesher-package is now on CRAN, but for some arch's might be a
little slow, so if you run into problems with the upgrade (not being
able to install/compile 'fmesher'), then try manually

options(repos=c(
inlabruorg = "https://inlabru-org.r-universe.dev",
INLA = "https://inla.r-inla-download.org/R/testing",
CRAN = "https://cran.rstudio.com"))
install.packages("fmesher")


and the upgrade R-INLA.

Let us know if there are any issues.
