Update to properties for more details (make knots better than core on…

Mempool Statistics in Properties section:
I added a section in the sidecar function to retrieve and format:
 - Max Mempool Size in MB
 - Current Mempool Usage in MB and as a percentage
 - Mempool Transaction Count

I have also made and tested this to ensure it works flawlessly.
