Add readme file in every folder in src to refer to the detailed documentation in doc #253
Description
Background
Currently the documentation is in a separate folder than src/ which can be difficult to navigate through the src and the docs at the same time.
The idea is to make in each of the important src subfolders, a Readme file that points to the different important documentation. For example, in src/ecdsa/ot_based_ecdsa, create a Readme.md pointing to DKG, ecdsa preliminaries and the multiple different ot based ecdsa documentations.

Acceptance Criteria
