textproc/jless: update to 0.9.0

v0.9.0 (2023-07-16)
==================

New features:
- A new command `ys` will copy unescaped string literals to the
  clipboard. Control characters remain escaped.
- The length of Arrays and size of Objects is now shown before the
  container previews, e.g., (`foo: (3) ["apple", "banana", \ 
"cherry"]`)
- Add a new family of "print" commands, that nearly map to the existing
  copy commands, that will simply print a value to the screen. This is
  useful for viewing the entirety of long string values all at once, or
  if the clipboard functionality is not working; mouse-tracking will be
  temporarily disabled, allowing you to use your terminal's native
  clipboard capabilities to select and copy the desired text.
- Support showing line numbers, both absolute and/or relative. Absolute
  line numbers refer to what line number a given node would appear on if
  the document were pretty printed. This means there are discontinuities
  when in data mode because closing brackets and braces aren't
  displayed. Relative line numbers show how far a line is relative to
  the currently focused line. The behavior of the various combinations
  of these settings matches vim: when using just relative line numbers
  alone, the focused line will show `0`, but when both flags are enabled
  the focused line will show its absolute line number.
  - Absolute line numbers are enabled by default, but not relative line
    numbers. These can be enabled/disabled/re-enabled via command line
    flags `--line-numbers`, `--no-line-numbers`,
    `--relative-line-numbers` and `--no-relative-line-numbers`, or via
    the short flags `-n`, `-N`, `-r`, and `-R` respectively.
  - These settings can also be modified while jless is running. Entering
    `:set number`/`:set relativenumber` will enable these settings,
    `:set nonumber`/`:set norelativenumber` will disable them, and
    `:set number!`/`:set relativenumber!` will toggle them, matching
    vim's behavior.
  - There is not yet support for a jless config file, so if you would
    like relative line numbers by default, it is recommended to set up
    an alias: `alias jless=jless --line-numbers --relative-line-numbers`.
- You can jump to an exact line number using `<count>g` or `<count>G`.
  When using `<count>g` (lowercase 'g'), if the desired line number is
  hidden inside of a collapsed container, the last visible line number
  before the desired one will be focused. When using `<count>G`
  (uppercase 'G'), all the ancestors of the desired line will be
  expanded to ensure it is visible.
- Add `C` and `E` commands, analagous to the existing `c` and `e`
  commands, to deeply collapse/expand a node and all its siblings.

Improvements:
- In data mode, when a array element is focused, the highlighting on the
  index label (e.g., "[8]") is now inverted. Additionally, a '▶' is
  always displayed next to the currently focused line, even if the
  focused node is a primitive. Together these changes should make it
  more clear which line is focused, especially when the terminal's
  current style doesn't support dimming (`ESC [ 2 m`).
- When using the `c` and `e` commands (and the new `C` and `E`
  commands), the focused row will stay at the same spot on the screen.
  (Previously jless would try to keep the same row visible at the top of
  the screen, which didn't make sense.)

Bug fixes:
- Scrolling with the mouse will now move the viewing window, rather than
  the cursor.
- When searching, jless will do a better job jumping to the first match
  after the cursor; previously if a user started a search while focused
  on the opening of a Object or Array, any matches inside that container
  were initially skipped over.
- When jumping to a search match that is inside a collapsed container,
  search matches will continue to be highlighted after expanding the
  container.
- [Issue #71 / PR #98]: jless will return a non-zero exit code if it
  fails to parse the input.

Other notes:
- The minimum supported Rust version has been updated to 1.67.
- jless now re-renders the screen by emitting "clear line" escape codes
  (`ESC [ 2 K`) for each line, instead of a single "clear screen" escape
  code (`ESC [ 2 J`), in the hopes of reducing flicking when scrolling.
