Addresses: https://qctrl.atlassian.net/browse/PA-2317

This pull request includes several changes to the qctrlopencontrols library, specifically within the driven_controls and dynamic_decoupling_sequences modules. The primary focus of these changes is to standardize the notation for the maximum Rabi frequency and improve the clarity of mathematical expressions.

Standardization of notation:

• Updated the notation for the maximum Rabi frequency from \Omega_{\rm max} to \Omega_{\mathrm max} in the new_primitive_control, new_bb1_control, new_sk1_control, new_scrofulous_control, new_corpse_control, new_corpse_in_bb1_control, new_corpse_in_sk1_control, new_corpse_in_scrofulous_control, and new_wamf1_control functions. [1] [2] [3] [4] [5] [6] [7] [8] [9]

Improvement of mathematical expressions:

• Corrected the LaTeX notation for the sinc function and other mathematical expressions in the new_scrofulous_control, new_corpse_control, new_corpse_in_bb1_control, new_corpse_in_sk1_control, and new_corpse_in_scrofulous_control functions. [1] [2] [3] [4] [5]
• Updated the Walsh function definition in the new_walsh_sequence function to use \mathrm for consistency.
