Issue with network paths on Windows systems

[abx78]

This works fine

julia> mydir = FileTree("C:\\Temp\\TestData")
C:\Temp\TestData/
├─ file-179.csv
└─ file-216.csv

julia> a = FileTrees.load(mydir) do test
       DataFrame(CSV.File(path(test)))
       end
C:\Temp\TestData/
├─ file-179.csv (3×7 DataFrame)
└─ file-216.csv (4×7 DataFrame)

This does not :(

julia> mydir = FileTree("\\\\Network\\TestData")
\\Network\TestData/
├─ layer-179.csv
└─ layer-216.csv

julia> a = FileTrees.load(mydir) do test
       DataFrame(CSV.File(path(test)))
       end

This is the error:

After further investigation I realized the issue is caused by the FilePathsBase package, at the moment it does not support UNC paths.
https://github.com/rofinn/FilePathsBase.jl/blob/master/src/windows.jl#L42

this is a PR open since 2018 to fix the issue.
rofinn/FilePathsBase.jl#12

I am closing this issue, I will refer to that repository.
