Update to FriCAS 1.1.3

Changes:

- Added "jet bundle" framework  by Werner Seiler and Joachim Schue,
  which includes completion procedure and symmetry analysis for PDE.

- Better splitting of group representations (added Holt-Rees improvement
  to meatAxe).

- Added numeric versions of some elliptic integrals and few more elliptic
  functions.

- Speeded up FFCGP (finite fields via Zech logarithms).

- New experimental flag (off by default, set via setSimplifyDenomsFlag)
  which if on causes removal of irrationalities from denominators.
  Usually it causes slowdown, but on some examples gives huge speedup.
  It may go away in future (when no longer needed).

- Added experimental framework for theory of computations.

Bug fixes, in particular:

- Numerical solutions of polynomial systems have now required accuracy
  (SF 2418832).

- Fixed problem with crashes during tracing.

- Fixed a problem with nested iteration (SF 3016806).

- Eliminated stack overflow when concatenating long lists.
