    .SYNOPSIS
        Install a Posh-ACME certificate into a Windows certificate store.
 
    .DESCRIPTION
        This can be used instead of the -Install parameter on New-PACertificate to import a certificate with more configurable options.
 
    .PARAMETER PACertificate
        The PACertificate object you want to import. This can be retrieved using Get-PACertificate and is also returned from things like New-PACertificate and Submit-Renewal.
 
    .PARAMETER StoreLocation
        Either 'LocalMachine' or 'CurrentUser'. Defaults to 'LocalMachine'.
 
    .PARAMETER StoreName
        The name of the certificate store to import to. Defaults to 'My'. The store must already exist and will not be created automatically.
 
    .PARAMETER NotExportable
        If specified, the private key will not be marked as Exportable.
 
    .EXAMPLE
        Install-PACertificate
 
        Install the certificate for the currently selected order to the default LocalMachine\My store.
 
    .EXAMPLE
        Get-PACertificate example.com | Install-PACertificate
 
        Install the specified certificate to the default LocalMachine\My store.
 
    .EXAMPLE
        Install-PACertificate -StoreLocation 'CurrentUser' -NotExportable
 
        Install the certificate for the currently selected order to the CurrentUser\My store and mark the private key as not exportable.
