Detect uppercase date time formats #165
This patch allows to detect uppercase date time formats (used at least by libreoffice). A test case is included. Note that the test fails due to different autogenerated col_names in xls and xlsx
EDIT: Excel is able to parse the file so I assumed that readxl should be capable too, otherwise the pull request would have gone to libreoffice.
I updated the commit message. Please note that readxl has been like this for 8 months, so the chances of this being merged in the next few days are not huge. Hopefully eventually someone will work a bit on the package and will deal with the increasing number of pull requests.
(I am just another random readxl user, there is not much more I can do)
