v0.2.1

Sindbad v0.2.1

Diff since v0.2.0

• Use OmniTools only via SindbadTEM; remove direct OmniTools dependency from Sindbad.
• Setup and other modules now obtain Table and normalize_path_separator from Sindbad’s re-exports (from SindbadTEM) instead of loading OmniTools directly.
• Rebuild and update API documentation (DataLoaders, MachineLearning, ParameterOptimization, Setup, Types).
