Update windows path separator in executable search

[cswartzvi]

Using version 0.1.1 on windows, condax install appears to run successfully, however no batch file is created in ~/.local/bin. This issue can be traced to the identification of executables using the conda-meta JSON data. The relative paths listed under the files key are (to the extend of my research) always expressed with forward slashes. This is simple fix to get condax working on windows in anticipation of a more robust check.

Interesting 😮 the debug log from the failed windows test clearly shows the candidate executables extracted from the conda-meta JSON as containing backslashes. However, when I examine the same debug line on my system (using this branch) I see forward slashes. Furthermore, when I install jq (again using this branch) and examine ~/.condx/jq/conda-meta/jq-1.6-haa95532_1.json I also see forward slashes. Not sure what is going on, but regardless, I will write a more robust check that accommodates the variability in windows path separators.

Alright, so this appears to be working now both on windows systems and in the tests. Apologies for the delay!
