Load Mainnet ProtocolSchedule Faster and With Less Memory Usage (#1688)
The change from create to DEFAULT was something that I saw was needed to keep the reference tests performant in the upcoming EIP-2718 changes. The change from reading the whole mainnet genesis to reading just the config portion came from OutOfMemoryErrors in the reference tests when running normalizeKeys. Also moved them to ProtocolTestFixture since they're only used by tests. Signed-off-by: Ratan Rai Sur <ratan.r.sur@gmail.com>pull/1690/head
