v1.3.0

Updates

• Minimum supported Python version increased to 3.8
• Adds I/O methods for saving and loading populations
• Clean up required dependencies (no longer require numpy, use pip install platypus-opt[full] to get all optional dependencies)

Breaking Changes

This version moved / renamed the default_variator, default_muator, and nondominated_cmp methods. Since this will break any code depending on these methods, they are being restored in version 1.3.1 but are being marked as deprecated. Please update your code as these will be removed in a future version.
