Adding SCORE, DAS and NoGAM algorithms to `gCastle`

[AlxndrMlk]

Hi team,

As recently demonstrated by Montagna et al. (2023), score matching algorithms like SCORE, DAS and NoGAM might overperform other algorithms under certain assumption violations.

This makes them attractive candidates for practical applications, especially under some relatively mild assumptions regarding the data generating process.

I believe they would be a great extension of gCastle's unique algorithm arsenal.

Curious to hear your thoughts.
