This release enables (or more accurately, re-enables previously disabled) pegged
orders, meaning they're finally here 🎉

The Ethereum bridge also received some work - in particular the number of
confirmations we wait for on Ethereum is now controlled by a governance
parameter. Being a governance parameter, that means that the value can be
changed by a governance vote. Slightly related: You can now fetch active
governance proposals via REST.

1️⃣ We also switch to Buf for our protobuf workflow.
This was one of the pre-requisites for opening up our api clients build
process, and making the protobuf files open source. More on that soon!
2️⃣ This fixes an issue on testnet where votes were not registered when
voting on open governance proposals. The required number of Ropsten VOTE
tokens was being calculated incorrectly on testnet, leading to all votes
quietly being ignored. In 0.30.0, voting works as expected again.

New:

#2732 Add REST endpoint to fetch all proposals (/governance/proposals)
#2735 Add FeeSplitter to correctly split fee portion of an aggressive order
#2745 Add transfer bus events for withdrawals and deposits
#2754 Add New Market bus event
#2778 Switch to Buf 1️⃣
#2785 Add configurable required confirmations for bridge transactions
#2791 Add Supplied State to market data
#2793 🔥Rename marketState to marketTradingMode, add new marketState enum (ACTIVE, SUSPENDED or PENDING)

#2838 Add bond and fee transfers
