Log message:
(textproc/R-htmlTable) updated 1.13.1 to 2.2.1

Changes fro 2.2.1
-----------------
* The `txtInt` handles `NA` more gracefully.

Changes fro 2.2.0
-----------------
* Added `htmlTable_args` attribute for making modifications to the
  final table easier

Changes fro 2.1.0
-----------------
* Added options for how the empty spacer cell appears (see
  `addHtmlTableStyle()` spacer.* options)
* Fixed ignored `align.header`
* Fix for wrapped styles (issue #80)

Changes for 2.0.1
-----------------
* Fix for txtRound not handling negative numbers (issue #76)
* Fix bug for `hidden.rgroup` & `hidden_tspanner` in `tidyHtmlTable`
* Documentation improvements & switched to markdown docs

Changes for 2.0.0
------------------
* Added theming and styling with `addHtmlTableStyle` and
  `setHtmlTableTheme` to reduce the cognitive burden of finding the
  right option within the docs. Note: this may impact your current
  tables and hence the major version (2.0.0).
* Changed so that `css.cell` is properly applied to rownames, cell
  fillers and the actual cells of interest (may impact the final
  layout!)
* Breaking change `tidyHtmlTable`: Moved to a fully tidyverse
  compatible system with tidyHtmlTable. This is a breaking change to
  the API as we switch from columns as strings to `tidyselect` syntax
  and as `gather`/`spread` have been replaced by
  `pivot_longer`/`pivot_wider` the default values have been updated in
  accordance with their defaults, e.g. `rnames = "name"` and `value =
  "value"`.
* Breaking change `tidyHtmlTable`: Sorting of rows is skipped as we
  may have situations with repeating inputs and this can easily be
  performed pre-function by calling `dplyr::arrange`. This has
  furthermore the desirable feature that any custom sorting is
  retained.
* Added *mso-number-format* to help (Issue #63) - thanks Rasmus Hertzum
* txtRound can now add txtInt when formatting the integer section for
  easier readability
* Added htmlTable css options - they should all start with
  `htmlTable.`
* `pos.caption` now uses match.arg as expected
* Fixed proper S3 function definition for `htmlTable` with all the
  arguments
* Added `htmlTable.css.border` style option for allowing to choose
  border style. Also fixed bug with cgroup empty cells and vertical
  border.
* Added `htmlTable.pretty_indentation` option for skipping the
  stripping of all the tabs that was required due to old Pandoc bug.
* Added `attr(x, "html") <- TRUE` by default and UTF-8 encoding on all
  outputted strings to mimic the `htmltools::HTML` function behavior.
* For simple tibble output the `tidyHtmlTable` can now be used to
  choose a column for the rnames argument
* The print statement now respects the `chunk_output_type` in Rmd
  files in RStudio
* `tidyHtmlTable` now accepts table function that allows switching to
  other table functions
* Added `css.header` style as using `css.cell` wasn't entirely
  intuitive (fixes issue #73)
Changes for 1.13.3
------------------
* Prepared for R 4.0

Log message:
Update all R packages to canonical form.

The canonical form [1] of an R package Makefile includes the
following:

- The first stanza includes R_PKGNAME, R_PKGVER, PKGREVISION (as
  needed), and CATEGORIES.

- HOMEPAGE is not present but defined in math/R/Makefile.extension to
  refer to the CRAN web page describing the package.  Other relevant
  web pages are often linked from there via the URL field.

This updates all current R packages to this form, which will make
regular updates _much_ easier, especially using pkgtools/R2pkg.
