    .SYNOPSIS
        Removes a Custom List from BloxOne Threat Defense

    .DESCRIPTION
        This function is used to remove named lists from BloxOne Threat Defense. These are referred to and displayed as Custom Lists within the CSP.

    .PARAMETER Name
        The name of the Custom List to remove.
        
        Whilst this is here, the API does not currently support filtering by name. (01/04/24)
        
        For now, you should instead use pipeline to remove objects as shown in the examples.

    .PARAMETER Object
        The Custom List Object. This accepts pipeline input from Get-B1CustomList

    .EXAMPLE
        PS> Get-B1CustomList | Where-Object {$_.name -eq "My Custom List"} | Remove-B1CustomList
