109.36.00

- In `Ascii_table` module, added support for displaying table using ASCII characters instead of Unicode.

  This is motivated by the need to use `Core_bench` in contexts where
  the extended ASCII character set is not suitable for displaying
  tables.

  The default style is the following:

  ```
  ┌─────────────────┬───────────┬──────────┐
  │ Name            │ Time (ns) │ % of max │
  ├─────────────────┼───────────┼──────────┤
  │ quick_stat      │     93.11 │   100.00 │
  │ counters        │     33.24 │    35.70 │
  │ allocated_bytes │     37.03 │    39.77 │
  └─────────────────┴───────────┴──────────┘
  ```

  The new style is as follows:

  ```
  $ ./test_bench.exe gc -q 0.5 -ascii
  Estimated testing time 1.5s (change using -quota SECS).

    Name              Time (ns)   % of max
   ----------------- ----------- ----------
    quick_stat            93.17     100.00
    counters              34.56      37.09
    allocated_bytes       37.06      39.78
  ```
