Implement support for ScalaPy in Scala 3

The name Scala comes from the word scalable, and true to that name, the Scala language is used to power busy websites and analyze huge data sets. Scala is one of the leading languages in implementation of big data systems. It is widely used in streaming data. Similarly, Python has become the language of choice for data scientists with its many high-quality scientific libraries. ScalaPy is that bridge which gives an opportunity to use Python libraries in Scala. Last year a new version of Scala was introduced. At the moment it is not released but Scala 3 brings many new features and changes. The aim of this project is to discover those new features and implement support for ScalaPy in Scala 3. ScalaPy will possibly help Scala 3 to become more popular among scientists and maybe this will be the core moment in combining data processing and data analysis worlds in Scala 3.
