v2.9.1

Upgrade priority: Low. No major changes when on at least 2.8.2. Users encouraged to upgrade to at least that patch.

• Breaking change The API will now not attempt to queue calls made while not connected and send on connection. Rather when making a call and the RPC node is not connected, an error will be thrown.

Contributed:

• Add typegen capability for custom RPCs (Thanks to https://github.com/holygits)

Changes:

• Remove rpc-core send queue, only allow sends while connected
• Adjust staking derive for electedInfo to contain details of current validators
• Extract identity-only derive from accounts.info for simpler reusability
• Add types for Substrate master node (to allow for consistent swapping to MultiAddress)
• Adjust Bytes with .slice to be consistent for Uint8array extensions (already released in 2.8.2 as a bugfix)
