Benchmark for calling ConnectBlock on a block with many inputs
Requires placing `block-107134.tar.gz` (containing the block, and a fake CoinsDB containing its inputs) into the base directory of the repository.
To facilitate generation of the fake CoinsDB, an additional field `valuesZat` has been added to `getrawtransaction` containing the integer number of zatoshis instead of a decimal number of ZEC.
Closes#2355.
