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
