VS Deploy should clean up OTA folders and files

[doingnz]

Describe the solution you'd like
VS Deploy should clean up folders and files left over from previous OTA firmware updates. Currently the Deploy process in VS is trying to do the correct thing (see log below), but it appears it may not have the permission on the Meadow to erase some files and folders and therefore the delete fails.

Describe alternatives you've considered
Manually list files and erase them individually with meadow file list
Erase the Meadow device and re-deploy the latest firmware to "reset" to "factory state".

Additional context
Currently when doing deploy from Visual Studio, it gets a list of ALL files on the Meadow and attempts to clean-up by deleting files not part of the deploy but on the Meadow, and delete files that are different and will be replaced in the deploy. Some delete fail.
