Update README.md

general outline of the enhanced installation instructions:
- The fist section describes the general steps and notes one can also just download a pre-built binary
- the second section is a table with a dependency overview, containing more info and rationales for the dependencies thus effectively informing the end-user of what he/she is installing and why
- the third and final section consists of the platform specific "copy-paste ready" instructions
Update README.md

Updating the dependency table TODO
 - does kotnetcli use python2 specific things or should it also run fine in a python3 environment?
 - do you need a python interpreter for running the pre-built binary?
