feat: bugfix_single_subplot_pulse_diagram

Explanation of changes

This MR implements various improvements regarding plotting.

• Performance : time for plotting was extremely long. Only one plot per port now is used. In linear signals (ramp and square pulses) the number of points used to plot the signal is reduced to the bare minimum

• Repetition : Discarded all the useless points that were created a zeros in the plot due to repetition. Timing show only the first repetition

• Offset : Now pulse are properly displayed including offsets and waveforms

• New functions have been added

Motivation of changes

Increased performance and memory efficiency.

• New code is covered by unit tests (or N/A).
• New code is documented and docstrings use numpydoc format (or N/A).
• New functionality: considered making private instead of extending public API (or N/A).
• Public API changed: added @deprecated and entry in deprecated code suggestions (or N/A).
• Newly added/adjusted documentation and docstrings render properly (or N/A).
• Pipeline fix or dependency update: post in #software-for-developers channel to merge main back in or update local packages (or N/A).
• Tested on hardware (or N/A).
• CHANGELOG.md for breaking changes and AUTHORS.md have been updated (or N/A).
• Update Hardware backends documentation if backend interface change or N/A
• Check whether performance is significantly affected by looking at the Performance metrics results.
• Windows tests in CI pipeline pass (manually triggered by maintainers before merging).
  • Maintainers do not hit Auto-merge, we need to actively check as manual tests do not block pipeline
