Add feature : No matching pattern for sheets parameter

[Raul-rp]

Please add the feature of pattern mismatch o r Negation of [...], matches characters not in the brackets for sheets parameter

For example:

SELECT * FROM read_sheets(['.xls', '.xlsx'], sheets=['![SheetToDiscard]']);

[redraiment]

That sounds reasonable, but it deviates from standard glob syntax and may cause confusion for users familiar with glob patterns. Let me consider this further.
