Pull request overview

This PR adds initial support for Disdromet RD-80 disdrometer processing by introducing a new RD-80 Level 1b converter and a new internal disdronator reader package, plus a small plotting tweak and a unit test + sample file.

Changes:

• Add rd802nc converter for Disdromet RD-80 and register it in cloudnetpy.instruments.
• Introduce new cloudnetpy.disdronator readers (RD-80 + Parsivel + LPM) and shared parsing utilities.
• Update plotting metadata to mask zeros for number_concentration, and extend mypy overrides for cftime.
