v2.1.1

[2.1.1] - 2024-01-03

Changed

• Rename internal matrix square-root from stretch_2 and stretch_2s to sqrt_2 and sqrt_2s. This does not affect the public API which remains unchanged as (matrix) square root sqrt(T).
• Remove an unused print statement in sqrt_2().

Fixed

• Fix the orientation of rotation_matrix(phi,2) for a rotation matrix around axis 2. Also fix the docs for rotation_matrix(phi,1) and rotation_matrix(phi,3).
