Added radius rescaling to simple env

[pandyah5]

Description

This PR implements dynamic rescaling of the entity radius as we 'Zoom In' or 'Zoom out' of the rendering. This fixes #1188 which mentions that keeping the radius constant when rescaling the coordinates leads to an illusion of fixed obstacles coming closer or moving away from each other when in reality they are fixed.

Files modified: simple_env.py
High-level overview: Extended the concept of cam_range and recorded the original cam_range to scale the radius

Fixes #1188 , Depends on None

Type of change

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• This change requires a documentation update [Mentioning this in the documentation may be helpful]

Screenshots

Notice how the zoom out effect is more intuitive in the dynamic resizing case

Apologies for necro-ing this PR. the maintainers of PZ went on a short hiatus and are now getting back to things.

Thanks for the fix! Looks good to go for me, once precommit is fixed then we can merge. :)

Gotcha, for the precommit I just need to modify the formatting of my files right? The tutorial failures seem unrelated to this PR.

@jjshoots I have modified the formatting and the pre-commit check passes now. Thanks for reviewing my PR!

PS: I just glanced over your website, your journey across the 'remote Pacific' is sooo cool. Is there a place where I can message you to learn more about it? 😄
