inlabru 2.14.1

Bug fixes

• Fix issue #293, where automated mapper construction for factor_contrast
  always used the alphabetically first level as contrast, instead of the
  factor-defined first level (2.14.0.9001)
• Fix eval_spatial<SpatRaster> to return factor data for pure factor layer
  extraction. Layer-specific terra::extract() may return integer instead of
  factor data, as multi-layer extraction would otherwise need to mix data of
  different types (2.14.0.9002)
• Check for "error" inheritance for input evaluation and other errors instead
  of "simpleError", as R > 4.6 uses more fine-grained error sub-classes in more
  cases than before (2.14.0.9004)

General updates

• Move fmesher from Depends: to Imports: to avoid unnecessary
  namespace clashes and encourage explicit fmesher declarations in user code
  (version 2.14.0.9003). Temporarily keep re-exporting fm_int and
  fm_pixels to avoid breaking outdated packages, for CRAN bugfix release
  2.14.1.
