spStack 1.1.3.99

• New model families: svcLMexact(), svcLMstack(), svcGLMexact() and svcGLMstack() for spatially varying coefficients model, and stvcLMexact(), stvcLMstack() for Gaussian spatially-temporally varying coefficients model.
• Faster, leaner and more robust backend: closed-form exact LOO for the Gaussian models, deletion updates for GLM LOO and K-fold CV, PSIS in C++, informative errors, and a new diagnostics element.
• Breaking changes: in spLMexact()/spLMstack() the inverse-gamma prior is on the noise variance sigmaSq; stacked fits store model.params and stacking.summary.
• New lean synthetic datasets simSpatial and simSpaceTime replace the old datasets and sim_spData(); all examples and vignettes use them. surfaceplot()/surfaceplot2() use a colorblind-friendly palette.
