Kujira Oracle Rest endpoint

Oracle token prices REST endpoint on @TeamKujira.

This list is notably incomplete. Right off the top: $AQLA is missing. There are others, but, importantly, the blue chips ($ETH, $BTC, $BNB) are there and the CØSMOS mainstays ($KUJI, $ATOM, $OSMO, $LUNA) are there with up-to-date prices.
