get_content_type dont find the correct answer

[VincentGuyader]

HI,

I have an .xlsx file, I copy and rename this file to have file.xlsx,file.csv,file.txt (I just change the extension)
This is what I obtain :

simplemagic::get_content_type("file.xlsx")
## [1] "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet"
simplemagic::get_content_type("file.xls")
## [1] "application/zip"
simplemagic::get_content_type("file.csv")
## [1] "application/zip"
simplemagic::get_content_type("file.txt")
## [1] "text/plain"

It will be perfect if all output could be "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet"

Regards

Thx for filing the issue! There are extra checks I can add into the zip binary header area for this. Shld be a quick add.

thks for your work on this.
If you need more test on this package , just ask !
If we could have a package on windows with zero dependencies and no compiled code it would be amaiing :)

don't hesitate to ask for more binary checks. while I'm not re-creating the libmagic library or file utility, adding in hardcoded checks riffed off of the magic file specs is pretty straightforward.

I just pushed an update that better handles excel, word and ppt with improper extensions and worked for a small series of local tests. kick the tyres when you get a chance and let me know if I need to tweak anything.
