Runner Environment (please complete the following information):

• OS: windows-2019
• Action version: v0.0.5

Additional context
Seems that the arguments to the tar command are not properly escaped on Windows which causes all directories to be concatenated (where path separators are expected). I think the relevant is here: https://github.com/satackey/action-docker-layer-caching/blob/master/src/LayerCache.ts#L59

I fixed this in v0.0.8 (#23).
