Features from optional dependencies

simx implicit feature

Enables simx

simx:

SimX provides Sim package extensions, for research and experimentation

Affects model_trait::DevsModel.event_rules_scheduling, model_trait::DevsModel.event_rules

console_error_panic_hook implicit feature

Enables console_error_panic_hook

The console_error_panic_hook crate provides better debugging of panics by logging them with console.error. This is great for development, but requires all the std::fmt and std::panicking infrastructure, so isn't great for code size when deploying.

wee_alloc implicit feature

Enables wee_alloc

wee_alloc is a tiny allocator for wasm that is only ~1K in code size compared to the default allocator's ~10K. It is slower than the default allocator, however.
