RSK Smart Bitcoin RBTC: Q3 Updates

Node Synch Improvements: Several performance improvements to blockchain long sync and the introduction of warp sync, will enable users to have their nodes ready to use in a fraction of the time currently required.

Meta Transactions: With the introduction of meta-transactions, users are relieved of dealing with gas prices, making the end user experience much better.

Garbage Collector: This feature reduces required blockchain storage significantly by deleting old and unnecessary information stored by the node.

Ethereum Native Contracts: We are adding support for EVM precompiled contracts not present in RSK Virtual Machine (pairing check, elliptic curve operations).
