feat<table model>: add tablemaster with paddleocr to detect and recognize table

[papayalove]

Motivation

To enhance the ability of table detection and recognition, we adopt a new table structure model——Tablemaster along with paddleocr to deal with tables. TableMaster is way faster than StructEqTable.

Modification

We add an option for table convertion. Unlike the StructEqTable, the new table model will ouput result in html codes.

Use cases (Optional)

Change the value of "model" in magic-pdf.json to switch to TableMaster.

{
  // other config
  "models-dir": "D:/models",
  "table-config": {
        "model": "TableMaster", // Another option of this value is 'struct_eqtable'
        "is_table_recog_enable": false, // Table recognition is disabled by default, modify this value to enable it
        "max_time": 400
    }
}
