Craftax prep for 5.0 release

[daphne-cornelisse]

Description

• Delete old profiling code [minor]
• Rendering: Make enchanted armour visible.
• Replace remaining Jaxisms with C native equivalents; do a pass to improve code readability
• Delete bloated craftax env code (total of 8132 lines)
• Delete old craftax files and deprecated tests
• Ensure craftax is playable (press shift to interrupt)

Parity test is at tests/craftax_parity.py

Evaluate using

bash build.sh crafax
./puffer eval

-> checked on macOS (with and without cpt) ❗️ note: build.sh and puffercpu need a couple adaptations to make eval work on my mac (different pr)

Next PR

• Separate craftax.h into one clean version and craftax_parity.h containing all the treefry rng logic.

Run parity test to original (output)

An NVIDIA GPU may be present on this machine, but a CUDA-enabled jaxlib is not installed. Falling back to cpu.
