Close() function not available when File opened with excelize.OpenReader()

[dwschulze]

I get an *excelize.File with

`f, err := excelize.OpenReader(file)`

where the file argument is a multipart.File. If I try to do

`defer f.Close()`

I get this error:

 _f.Close undefined (type *excelize.File has no field or method Close)_

If I get an *excelize.File with

`f, err := excelize.OpenFile(fileName)`

then I can call .Close() on it.

How do I assure that the excelize.File obtained from OpenReader() gets closed?

Thanks for your issue, this issue is duplicated with #1025, #1042, and #1091, the Close function has been introduced since v2.5.0, if you're using the version early than v2.5.0, needn't call this function.
