multiple providers to verify postdata

[heavyarms2112]

./postcli -verify -datadir post_data_dir -fraction 0.1 -fromFile 0 -toFile 5

Can we use multiple providers for faster/parallel verification?

Currently, it's not supported, but let's put it on some roadmap.

@heavyarms2112 you could call postcli many times in parallel using different providers with different files.
