Ergo Protocol Reference Client 5.0.7

Ergo protocol reference client 5.0.7. It contains following PRs:

• #1859 & #1944 & #1950 - the node now supports additional indexes (to store information about all the transactions, tokens, UTXOs, not just wallet-related), and a lot of additional requests on top of them, see /blockchain API methods. Additional indexes are switched off by default, to turn them on, set ergo.node.extraIndex = true in the config, to check availability of additional data on a public node, check new "isExplorer" flag in /info output

• #1940 & #1947 - more code imported from bootstrapping-with-UTXO-set-snapshot branch, still refactoring mostly at this point

• #1943 - network time got from a trusted NTP server is not used anymore (in particular, it led to header-timestamp-in-future issues)

• #1945 & #1951 - hot-fixes for mempool inconsistency (see #1952 )

• #1946 - sigma dependency (ErgoTree interpreter and ErgoScript compiler) are updated to 5.0.5 (release details https://github.com/ScorexFoundation/sigmastate-interpreter/releases/tag/v5.0.5 )

• #1948 - cross-compilation of ergo-wallet submodule with Scala 2.13

• #1949 - scala-sbt image updated for Docker build

In this version, rare improper BIP-32 seed secret generation from mnemonic (with 1/256 probability) is fixed. New wallet initialization is now using a new fixed procedure.

New API methods to work with mempool transactions: /transactions/unconfirmed/{txId} , /transactions/unconfirmed/byTransactionId/{txId}, /transactions/unconfirmed/byErgoTree, * /transactions/unconfirmed/inputs/byBoxId/{boxId}*, /transactions/unconfirmed/outputs/byBoxId/{boxId}, /transactions/unconfirmed/outputs/byErgoTree, /transactions/unconfirmed/outputs/byTokenId/{tokenId} , /transactions/unconfirmed/outputs/byRegisters
