Full Changelog: v0.5.0...v0.5.1

v0.5.0: SCS compat problems solution (#107)

Release notes:

Breaking changes

• Positional atol for predicate functions
  The predicate functions iscp, istni, istp, iscptp, iscptni, isidentity, and ispositive now accept the absolute tolerance (atol) as a second positional argument instead of a keyword argument.
  Upgrade tips: Change all occurrences of func(X; atol=val) or func(X, atol=val) to func(X, val). For example, iscp(Φ, 1e-10) instead of iscp(Φ, atol=1e-10).

• Removal of StatsBase dependency
  StatsBase.jl has been removed from the core dependencies of QuantumInformation.jl.
  Upgrade tips: If your code relies on StatsBase functions (like mean or var) that were previously available through this package, you must now explicitly add StatsBase to your project's Project.toml and import it.

New features & Improvements

• Enhanced Code Quality: Integrated Aqua.jl and JET.jl for rigorous automated testing of code quality and type stability.
• Improved Documentation: Added comprehensive docstrings to several core functions in src/channels/predicates.jl and src/utils.jl.
• Dependency Updates:
  • Expanded compatibility for SCS.jl to include version 3.x.
  • Expanded compatibility for Convex.jl to include version 0.16.x.
• CI Updates: Modernized the CI pipeline by focusing on current Julia versions and adding dedicated code quality stages.
