[Proposal] Update README

[Ilithy]

Hi;
Proposal for (slight) modifications of the Readme,

• To display the new features of TY,
• And (slightly) organize the file.

If you don't like it, don't hesitate to ask for changes, or to close this PR.

Thanks for your efforts in that!
I left some minor comments (that are not only related to your changes but also to the README in general), I'd appreciate if you could have a look at them and/or tell your opinion about it if you disagree at some points :)

Looks good to me now, thank you <3
