Update MerlinAU.sh with Memory Warnings

[ExtremeFiretop]

Added the discussed warnings both in the menu and the run script.

1. Integrate the RAM Check:
   Use the HasRouterMoreThan256MBtotalRAM() function to determine if the router has more than 256MB of total RAM. If it doesn't, and the ZIP file size is over 50MB, we should enforce the requirement of a USB-attached drive for storing the ZIP file.

2. Warning Message in Menu:
   Display a warning message in the main menu if the router has only 256MB of RAM and no USB drive is selected as the zip destination.

3. Also beautified the script menu and ROG prompts a bit.

4. Also moved the logging start location out of the regular user prompts as per the current standard.
