.SYNOPSIS
    Sets the data type of a property given the property name and the data type.
.DESCRIPTION
    Sets the data type of a property given the property name and the data type.
    This is needed as cmdlets such as Import-CSV pulls everything in as a string
    datatype so you can't sort numerically or date wise.
.PARAMETER TypeHash
    A hashtable of property names and their associated datatype
.NOTES
    # inspired by https://mjolinor.wordpress.com/2011/05/01/typecasting-imported-csv-data/
 
    Changes
    * reworked with begin, process, end blocks
    * reworked logic to work properly with pwsh and powershell
.EXAMPLE
    $csv = Import-CSV -Path .\test.csv | Set-Type -TypeHash @{ 'LastWriteTime' = 'DateTime'}
