add README.md (#39)

* Initialize the README.md with a sketch of the structure

* add warning and draft diagram

* add authors & years to schemes, add a pre-sketch of the 'development' section

* Readme: add link to Carlos talk on folding schemes

* readme: sketch sections: offchain & onchain decider, add todo for references

* readme: add example of FCircuit & folding

* Readme: add lib pipeline diagram, add decider code example

* add cyclefold-nova-diagram.png, decider-onchain-flow-diagram.png

* polish cli descriptions

* small update in the Warning box

* add sonobe naming

* add folding-main-idea-diagram.png

* missing sonobe renaming

* migrate part of the README.md to sonobe-docs

* rm imgs/, load them from sonobe-docs

* tiny update

* chore: start update README

* add acknolwedgments links and text, small polishing of the overall text

* extend folding introduction & sonobe overview

* img text alignment

* chore: update readme

* chore: typos, bits of reformulation, centering images

* chore: remove btc example since can not be used as is

* rm .vscode dir

* readme: merge the duplicated sections into a single one adapting the texts

* add Docs badge with link, update acknowledgments

* add ci & license badges

* fix cli link, add solc mention in solidity-verifiers/readme

* small polishing

* fix img alignment

* rm badges, the reasoning is:

- The License badge is not needed since there are already many links to
  the license both in the readme and in the GitHub UI
- The CI checks badge, already appears in the GitHub UI in the last
  commit preview at the main repo page. Furthermore, after some months
  of inactivity, the badge would be 'gray' as 'inactive'.
- The only badge that I was trying to get there is the 'docs' badge, to
  make it very clear that the docs page exists, but it was a bit to hard
  visually to have a single badge there, and furthermore the docs link
  already appears in the readme twice, and also in the GitHub UI
  right-panel.
