Rule request: AvoidNewObjectCmdlet

[iRon7]

The New-Object cmdlet is basically* legacy.
Since PowerShell V3.0 (12 years ago), PowerShell supports type accelerators which perform much better, see: PowerShell scripting performance considerations / object creation.

*) Exceptions left there (e.g. with the use of the [-ComObject] <String> parameter)

Therefore I think that it makes sense to have a AvoidNewObjectCmdlet rule.

You might also consider to link this type of rules to the #Requires -Version x.x statement.
(In case it doesn't exist in the concerned script: simply suppress the warning.)
