Returns all possible connections based on a from- or toChain.

This endpoint gives information about all possible tranfers between chains.
Since the result can be very large it is required to filter by at least a chain, a token, a bridge, or an exchange.
Information about which chains and tokens are supported can be taken from the response of the /v1/chains endpoint.
Information about which bridges and exchanges are supported can be taken from the response of the /tools endpoint.
