blacklist suggested packages

[dpastoor]

In some cases, not all suggested packages may be needed to be installed. Especially if significant system dependency load is introduced. For example, the sf package puts a significant GIS-based strain on installation of ggplot2.

In more extreme cases, wrapper packages, such as broom which provide interfaces over many packages can have huge suggested package loads

For example, the tidyverse broom package introduces the following suggested dependencies:

Suggests:
    AER,
    akima,
    AUC,
    bbmle,
    betareg,
    biglm,
    binGroup,
    boot,
    brms,
    btergm,
    coda,
    covr,
    emmeans,
    ergm,
    gam,
    gamlss,
    geepack,
    ggplot2,
    glmnet,
    gmm,
    Hmisc,
    irlba,
    knitr,
    ks,
    Lahman,
    lfe,
    lme4,
    lmodel2,
    lmtest,
    lsmeans,
    maps,
    maptools,
    MASS,
    Matrix,
    mclust,
    mgcv,
    muhaz,
    multcomp,
    network,
    nnet,
    orcutt,
    plm,
    poLCA,
    psych,
    purrr,
    rgeos,
    rmarkdown,
    robust,
    rsample,
    rstan,
    rstanarm,
    sp,
    speedglm,
    statnet.common,
    survival,
    testthat,
    xergm,
    zoo,
    tseries

This has arisen even in full-filled images, such as rocker/verse, where the xergm package does not install as of 2018-07-08

One solution is to provide a configuration option to check against a list of blacklisted packages before appending the suggested packages to the metapackage.
