nimble lock computes different hash on Windows than Linux/macOS

[iffy]

I filed this issue with nimble: nim-lang/nimble#1188

I don't really know what the fix is. The trouble is that this repo's .gitattributes file causes a different hash to be computed on Windows vs Linux/macOS, but I can understand why you want that file in this repo. Do you have a suggestion?

because of EOL conversion?

Yes, nimble computes a hash of the directory of installed packages for use in a lock file. On Windows, because of the EOL conversion, the hashes are different than those on Linux/macOS.

actually only one file is problematic tests/basic.mp should be treated as binary instead of text.
