Optimization of Underthesea Codebase Size

[rain1024]

As of release 6.8.0, the zipped version of the underthesea codebase measures 73.9MB, which is excessively substantial. Aiming to optimize, the goal is to reduce the size to approximately 10MB.

Proposed Strategies:

• Sub-repository Allocation for Datasets
  Migrate each dataset to individual sub-repositories to decentralize the storage and manage the codebase efficiently.

• Eliminate Storage of Binary Models
  Avoid the incorporation of binary models within the codebase. For reference, binary models are currently stored here:models/ws_crf_vlsp2013_20230727

• Code Refactoring
  Undertake a comprehensive refactoring of the code to improve its structure, readability, and maintainability, which can also contribute to reducing the overall size of the codebase.
