Add a simple chess board format

[Bonifatius94]

Issue:

• the bitboard encoding may be really nice for optimized draw-gen, but is rather hard to understand for deep learning algorithms
• therefore add a new bitboard data type and add conversion functions to facilitate usage by AI scripts

Suggested Solution:

• create a new data type (e.g. something like SimpleChessboard)
• make sure to add appropriate conversion functions between the simple and the efficient chess board format
• make the conversion easy-to-use by adding additional function args to ChessBoard_StartFormation() and ApplyDraw()
• also think of ways to implicitly convert the input data when given simple data formats

The simple chess board has been added to all module functions. Issue can be closed now.
