* support downloading blocks / states via JSON in addition to SSZ - slow, but needed for infura support - SSZ is still used when server supports it * use common forked block/state reader in REST API * fix stack overflows in REST JSON decoder * fix invalid serialization of `justification_bits` in `/eth/v1/debug/beacon/states` and `/eth/v2/debug/beacon/states` * fix REST client to use `/eth/...` instead of `/api/eth/...`, update "default" urls to expose REST api via `/eth` as well as this is what the standard says - `/api` was added early on based on an example "base url" in the spec that has been removed since * expose Nimbus REST extensions via `/nimbus` in addition to `/api/nimbus` to stay consistent with `/eth` * fix invalid state root when reading states via REST * fix recursive imports in `spec/ssz_codec` * remove usages of `serialization.useCustomSerialization` - fickle
