[Phase2] Mismatch reading/writing H

[Brechtpd]

There seems to be mismatch in the number of elements that are written to and then read from the phase1radix2 files for H.

• When writingdegree - 1 elements are written here
• When reading degree elements are read here

For me this results in the following error when reading the H elements running the examples:

thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: IoError(Custom { kind: UnexpectedEof, error: "failed to fill whole buffer" })'

Is there something I'm missing or is this indeed the problem?

Hey @Brechtpd, thanks for catching this. It seems you're right, I probably missed one of the changes I should have committed.

Small point - we use https://github.com/kobigurk/phase2-bn254/blob/master/powersoftau/src/bin/prepare_phase2.rs rather than verify.rs, since it doesn't perform re-verification of all the previous contributions.

I'll test that and commit the right version in the coming days - if you want to test it before, feel free to get in touch.

Fixed in #2.
