ENH: Adding 'hidden=True' to 'to_excel', or efficiently hiding some excel tabs?
I need to hide some excel tabs in an output from `to_excel`, and I'd like to do that with a parameter like `hidden=True`, but [no such parameter exists](https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.DataFrame.to_excel.html). The only solution I can find is [hiding the sheet manually with openpyxl](https://stackoverflow.com/questions/23157643/openpyxl-and-hidden-unhidden-excel-worksheets/23170772#23170772), but this is prohibitively slow for large files.

[My StackOverflow question on this](https://stackoverflow.com/questions/67154554/pandas-to-excel-with-sheets-being-hidden-or-efficiently-hiding-excel-tabs) is unanswered, which suggests I'm out of luck.

Testing openpyxl showed that we can't save .xlsxs without at least one visible tab, so it looks like this would only work like so:

```
writer = pd.ExcelWriter(filename, engine='xlsxwriter') 
with writer:
    df.to_excel(writer, sheet_name='df')
    df.to_excel(writer, sheet_name='2nd tab')
```

Would adding `hidden=True` to `to_excel` be practical?
