[library manager] CAN (Adafruit Fork)

this is a fork to add support for the SAME51, as sandeepmistry/arduino-CAN#57 has not been merged and folks want to use the library manager to install

Hi @ladyada. I spotted a couple issues:

• The library.properties name value contains the prohibited characters ( and ).
• The library.properties name value at the time of the last tag was "CAN", which has already been taken by Sandeep's library. The indexer works from tags, so it won't recognize an updated name value if it isn't in the latest tag.

I think it will all be good if you update the name value and then create a tag. After doing that, please comment here so we'll know we can proceed.
