An empty TransportOut means that no waybill has been added.

wuliu: Fixed the problem that the click event was not correctly added to the return waybill added on the confirm sign for page

Keep it simple.

The previous implementation was not a good idea.

In the latest openpyxl, `openpyxl.writer.excel.save_virtual_Workbook` method is deprecated.

Read the `data-value_type` attribute from the th tag of the table.
If not defined, the default is string type.

Currently only three value types are supported: str, int, float.

This facilitates sorting operations in the generated Excel sheet.

Used to replace ExpireLruCache.
And refactor the code.

Different decorated functions will be cached separately.

wuliu: forms: WaybillForm: When there is no optional Department in `src_department`, an empty value is allowed to be selected

When there is no waybill in the TransportOut, `total_cargo_num`, `total_cargo_volume`, `total_cargo_weight` should be displayed correctly.

Exception:
