BIP-0157: increase max getcfilters request to 1k blocks

In this commit, we effectively revert #699 by allow clients to request
filter for up to 1k consecutive blocks. Testing in the field has shown
that applications are able to reduce perceived latency from syncing to
full functionality after an app has been offline for several days by
batching requests for filters. A value of 100 would mean each additional
day behind adds an additional round trip, resulting in 10s of
seconds of lag after just a few days of being offline. A value of ~1k
allows implementations to catch up with roughly a week's worth of
filters in a single round trip.
