Here is a new version of `org-table-to-lisp'. Why a new version?

- Because it is more than 3x faster than the current one.
  Bench-marked on a 3822 rows by 16 columns Org table
  - current: 0.405 seconds
  - new one: 0.122 seconds
  on Emacs 30.0.50 with native compilation
  The speedup is achieved with or without native compilation.

- Because it does not use regexps anymore.
  It uses `following-char'
  instead of `re-search-forward'
  Therefore the global regexp state is no longer clobbered.

- Because after a 120x speedup in May 2020
  (by Nicolas Goaziou and myself)
  it is funny to discover yet another way to a 3x speedup.

- Because org-table-to-lisp is a basic
  building block of Org Mode, used in
  - table alignment
  - table export
  - Babel
  - plotting
  - table transposition

- Because this version is a drop-in replacement.
  The overall algorithm does not changed.

I ran all the standard unit tests of Org Mode as of [2024-02-24]. All went as expected.

Have fun
Thierry
