Fixes #159

[hustf]

Running this PR locally shows the same problems with libgeotiff.dll. Pinning ArchGDAL to v0.10.3 does not help.

This should probably be its own issue, because the installation problem now also occurs on the latest release of GeoArrays. The offending package is not obvious. So I tried updating my previously working environment (BitmapMaps) which had a working current-release GeoArrays, this also errored. The offending library is probably one of these:

(BitmapMaps) pkg> update

Sorry, the errors stem from a faulty release upstream, see yeesian/ArchGDAL.jl#427. Workaround is to run add PROJ_jll@901.300 GDAL_jll@301.900.

That fixes the install. There's a failed test (roundoff related?), but interestingly:

Bandnames: Error During Test at C:\Users\f\.julia\dev\GeoArrays\test\test_io.jl:112
  Got exception outside of a @test
  IOError: unlink("C:\\Users\\f\\AppData\\Local\\Temp\\test_bandnames.tif"): resource busy or locked (EBUSY)

That fixes the install. There's a failed test (roundoff related?), but interestingly:

That was due to the COG driver, at writing it launches an async process to write the overviews to the file, locking it. I've sprinkled earlier destroys throughout the codebase, hopefully you can run your code without locking files.

Can you post/make a new issue about the failed roundoff related test? Rounding numbers is always subtle, but all CI platforms are green, so I also wonder about your OS/platform.
