fix: Adding table readme

[finxlfantasy]

Description

Problem*

Making readme shorter by removing redundant text, and replacing it instead with a table.

Resolves #49 (comment)

Summary*

Replaces the long text in the feature section with a table.
Example as such:

features	halo2-pse	halo2-axiom
feature X	supported	supported
feature Y	supported	not supported
feature Z	not supported	supported

PR Checklist*

• I have tested the changes locally.
• I have formatted the changes with Prettier and/or cargo fmt on default settings.

Thank you Ethan, was my first PR lol.
By the way do you work with Aztec?

I've been learning Rust recently, and found it nice there is a DSL that's Rust based. Also looked at their ACVM docs.

[Ethan-000]

i worked with them during the summer. if you are interested in compilers and rust feel free to work on some issues there. they are generally nice and should be willing to get you started

[finxlfantasy]

Nice! Yeah i'm really passionate about cryptography and security. Had some ideas to specialise in the niche of Rust smart contract auditing and/or development. I kind of have a fundamental understanding of the theory and math when it comes to zk and such.

[Ethan-000]

Yeah its a very interesting field 😂. I also like rust, zk, math etc 🤝
