Mark Spanbroek 53999c74d3 Provide all gas to precompiles
Rationale: subtracting 2000 from the provided gas seems
arbitrary, and doesn't provide any benefits. Whether
verify() fails with an out-of-gas error, or returns
'false', in both cases the proof is not verified.

Mark Spanbroek 3b6f7b8ec7 Rename _Q -> _R
Using 'r' for the size of the scalar field is
standard practice.

Mark Spanbroek f413f1ea64 Represent elements from field F_{p^2} as `real + i * imag`
Reason: Circom and Ethereum EIP-197 both represent these
elements as arrays of two elements, but they do it in
reverse order of each other. This change makes it explicit
which number is the real part, and which number is the
imaginary part.
