<#
.SYNOPSIS
    Registers a global event processor that runs on every event before it is sent to Sentry.
.DESCRIPTION
    The script block receives the Sentry event via the automatic variable $_ (matching the
    convention used by Edit-SentryScope). Return the event to send it, or $null to drop it.
.EXAMPLE
    PS> Add-SentryEventProcessor { $_.SetTag('host', $env:COMPUTERNAME); $_ }
.EXAMPLE
    PS> Add-SentryEventProcessor {
            if ($_.Message -match 'secret') { return $null }
            $_
        }
