Fixed issue with getting local group members if membership contains an entry with an orphaned SID

Fixed issue with getting local group members being blank if any member of that group contains an orphaned SID. Fix #31

Description

Added a function called Get-LocalGroupMembership to get local group members that does not have an issue with group members with an orphaned SID. The original author of the Get-LocalGroupMembership function is Boe Prox: https://github.com/proxb/PowerShell_Scripts/blob/master/Get-LocalGroupMembership.ps1 The function has been modified slightly so that the output is compatible with the native Get-LocalGroupMember (to prevent re-work)

Motivation and Context

Solves issue: https://github.com/AsBuiltReport/AsBuiltReport.Microsoft.Windows/issues/31 Without this fix, if a member of any of your local groups SID could not be resolved, the output for that group membership would be blank.
