Add ability to allow skipping of open/unreadable files

[allanoro]

When trying to create an archive using Compress-Archive, the cmdlet will always fail if it comes across a file that is currently in use elsewhere, or is unreadable. I have an example of the error it will throw below.

What I would like is a switch which will allow Compress-Archive to skip any in use, or unreadable files and continue without terminating.

I have found this issue in all versions of PS6, and also now in PS7.

ZipArchiveHelper : Could not find file '*file in use*'.

This behavior occurs by default now.
