powershell script to create new post for hugo with good file name like 2022-12-12_my-awesome-title

hugonew.ps1

## This is my file hugonew
##
## 1. Place this file where your helper scripts are. For example I have dropbox folder "my_scripts".
##    Then add this folder to path variable.
## 2. cd to folder of your hugo blog and type: 
##  hugonew 'my awesome new nice title'
##
## this will create file 2022-12-12_my-awesome-new-nice-title.md in content/posts folder (if today is 2022-12-12)

## Some dummy ConvertTo-Slug function. scroll to bottom to see code.
## I have no idea how to properly import function so I just copy pasted from https://github.com/kns7/KNSHelper
## At least now this file has no dependencies ;)
