- Adds the logic to support multi-instances folding in HyperNova's
AugmentedFCircuit & IVC.
- Adds also methods to generate new LCCCS & CCCS instances that don't
depend on the main folding chain, to be folded in in the next step
- Updates CycleFold circuit & methods to work other folding schemes than
  Nova, adapting it to fold multiple points per circuit (instead of
2-to-1 as till now)
- Handle multi-instances folding in the FoldingScheme trait
  interface, which expects 'None' in Nova, and 'Some' in HyperNova &
other multi-folding schemes.

* 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.
