Add support for Minuteman Endeavor ED2000RM2U #3152
Description
Was given this sweet (tho discontinued) 2000VA UPS for free out of a decommissioned rack and I replaced the batteries. Not only is it more powerful and with a longer runtime than my APC 1500 Pro, but also True Sine Wave, so my lights and other non-PC loads don't flicker and do weird stuff! Sadly, it doesn't seem to be compatible with NUT, which is a real bummer as that's what I use to get all my servers/Pis/gaming PC to shut down together when the battery gets low. Tried usbhid-ups, belkin, and blazer_usb drivers but they don't spot anything.
The unit reports as a Delta brand HID UPS (possible Minuteman rebrands/white-labels their UPSes from another vendor?)

It seems that Minuteman is a pretty obscure brand with few Google results so I suppose I shouldn't be too surprised it isn't supported. But I did see that a pull request for the PRO1500RT2U model was accepted. Perhaps this will make it easier to support, if the protocol is similar. Both appear to be compatible with their same "SentryHD" software.
