Feature request: getting excel worksheet names and index only

[13minutes-yt]

getting --metadata c to be performed on an excel file takes some time for huge excel files. Is it possible to get the sheet name and the index only thereby cutting the time to process all the rows and columns( like an argument -a or --metadata a). I am currently using csvtk xlsx2csv input.xlsx -a which is much faster than qsv since it gets only sheetname and index. (Note: qsv is blazingly faster in outputting csv :) ).

This is a good request that can be quickly implemented. Didn't realize getting all that metadata took time...

Created #1698

I compiled it from source. still slow. is there something missing?

@13minutes-yt I was still fetching range data... that must be the slowdown. Fixed it

Can you give it a try and confirm?

All good. time dropped from 10.7 sec to 0.16 sec on my 57mb xlsx file with 330,000 rows. 😄

Tweaked it a bit more to return sheet type and visible info - already got the info in the sheet struct, so might as well...
