Binary Registry bug within PSDesiredStateConfiguration "Registry" Resource

Describe the bug
Attempting to set a binary registry key to 0 will result in the key being set to "zero-length binary value" due to a bug with the registry resource parsing the value of 0 into a binary format.

To Reproduce
Steps to reproduce the behavior:

1. Create a test configuration containing the following:

Configuration TestConfig {

 Import-DSCResource -ModuleName 'PSDesiredStateConfiguration'
 
 Nodename $Nodename 
 {
       Registry 'Registry(INF): HKLM:\System\CurrentControlSet\Control\Lsa\FullPrivilegeAuditing'
      {
       ValueName = 'FullPrivilegeAuditing'
       ValueType = 'Binary'
       Key = 'HKLM:\System\CurrentControlSet\Control\Lsa'
           ValueData = 0
           Ensure = "Present"
           Force = $True
        }
 }

}

2. Generate a MOF and push the configuration.
3. Check the HKLM:\System\CurrentControlSet\Control\Lsa registry key, it will be set to "Zero-Length Binary Value."
4. Set the valuedata to 1, and it will parse correctly, resulting in the key being set to "01"
5. Regardless of how you attempt to set the "00" value, it will result in the "Zero-Length Binary Value

Expected behavior
HKLM:\System\CurrentControlSet\Control\Lsa registry key should be set to "00"

Screenshots

Additional context
Work-around is importing the xPSDesiredStateConfiguration module and using the xRegistry resource, which will parse the value of "0" into a binary key of "00"

Example:

Configuration TestConfig {

 Import-DSCResource -ModuleName 'xPSDesiredStateConfiguration'
 
 Nodename $Nodename 
 {
       xRegistry 'Registry(INF): HKLM:\System\CurrentControlSet\Control\Lsa\FullPrivilegeAuditing'
      {
       ValueName = 'FullPrivilegeAuditing'
       ValueType = 'Binary'
       Key = 'HKLM:\System\CurrentControlSet\Control\Lsa'
           ValueData = 0
           Ensure = "Present"
           Force = $True
        }
 }

}
