feat!: rewrite the project in Python (#133)

# Description

It turned out that parsing of compiled classes is not the best option
especially if multiple programming languages are involved. This rewrite
analyzes the source code.

At the moment, Rest Api calls/endpoints are supported only. No Dot model
is available.
