We're re-gossiping old transactions -- this change eagerly checks them, at the expense of moving the checkpointer more often.

This PR uses Greg's tx index lookup to take a request key and produce an SPV transaction output proof. The workflow is as follows:
Lookup the index of the transaction on the current (source) chain, producing a block height and block hash.
Using the block height, lookup the specific index of the transaction in the block associated with that height.
Construct a transaction output proof using the SPV api for the given target chain id, at the blockheight associated with the transaction, at its index in the block.
Return this as unpadded B64url-encoded text.
