(textproc/R-stringr) Updated 1.4.0 to 1.5.0

# stringr 1.5.0

## Breaking changes

* stringr functions now consistently implement the tidyverse recycling rules
  (#372). There are two main changes:

    *  Only vectors of length 1 are recycled. Previously, (e.g.)
       `str_detect(letters, c("x", "y"))` worked, but it now \ 
errors.

    *  `str_c()` ignores `NULLs`, rather than treating them as length 0
        vectors.

    Additionally, many more arguments now throw errors, rather than warnings,
    if supplied the wrong type of input.

* `regex()` and friends now generate class names with `stringr_` prefix (#384).

* `str_detect()`, `str_starts()`, `str_ends()` and `str_subset()` now error
  when used with either an empty string (`""`) or a `boundary()`. These
  operations didn't really make sense (`str_detect(x, "")` returned `TRUE`
  for all non-empty strings) and made it easy to make mistakes when programming.

## New features

* Many tweaks to the documentation to make it more useful and consistent.

* New `vignette("from-base")` by @sastoudt provides a comprehensive \ 
comparison
  between base R functions and their stringr equivalents. It's designed to
  help you move to stringr if you're already familiar with base R string
  functions (#266).

* New `str_escape()` escapes regular expression metacharacters, providing
  an alternative to `fixed()` if you want to compose a pattern from user
  supplied strings (#408).

* New `str_equal()` compares two character vectors using unicode rules,
  optionally ignoring case (#381).

* `str_extract()` can now optionally extract a capturing group instead of
  the complete match (#420).

* New `str_flatten_comma()` is a special case of `str_flatten()` designed for
  comma separated flattening and can correctly apply the Oxford commas
  when there are only two elements (#444).

* New `str_split_1()` is tailored for the special case of splitting up a single
  string (#409).

* New `str_split_i()` extract a single piece from a string (#278, @bfgray3).

* New `str_like()` allows the use of SQL wildcards (#280, @rjpat).

* New `str_rank()` to complete the set of order/rank/sort functions (#353).

* New `str_sub_all()` to extract multiple substrings from each string.

* New `str_unique()` is a wrapper around `stri_unique()` and returns unique
  string values in a character vector (#249, @seasmith).

* `str_view()` uses ANSI colouring rather than an HTML widget (#370). This
  works in more places and requires fewer dependencies. It includes a number
  of other small improvements:

    * It no longer requires a pattern so you can use it to display strings with
      special characters.
    * It highlights unusual whitespace characters.
    * It's vectorised over both string` and `pattern` (#407).
    * It defaults to displaying all matches, making `str_view_all()` redundant
      (and hence deprecated) (#455).

* New `str_width()` returns the display width of a string (#380).

* stringr is now licensed as MIT (#351).

## Minor improvements and bug fixes

* Better error message if you supply a non-string pattern (#378).

* A new data source for `sentences` has fixed many small errors.

* `str_extract()` and `str_exctract_all()` now work correctly when `pattern`
  is a `boundary()`.

* `str_flatten()` gains a `last` argument that optionally override the
  final separator (#377). It gains a `na.rm` argument to remove missing
  values (since it's a summary function) (#439).

* `str_pad()` gains `use_width` argument to control whether to use the total
  code point width or the number of code points as "width" of a string \ 
(#190).

* `str_replace()` and `str_replace_all()` can use standard tidyverse formula
  shorthand for `replacement` function (#331).

* `str_starts()` and `str_ends()` now correctly respect regex operator
  precedence (@carlganz).

* `str_wrap()` breaks only at whitespace by default; set
  `whitespace_only = FALSE` to return to the previous behaviour (#335, @rjpat).

* `word()` now returns all the sentence when using a negative `start` parameter
  that is greater or equal than the number of words. (@pdelboca, #245)
