Prop 221: Injective Exchange dApp Update: Market Parameter Changes

Summary
This proposal updates the BTC/USDT perp maintenance margin ratio and price/quantity tick sizes for certain markets.
Background
The community has expressed the desire to lower the BTC/USDT perp maintenance margin ratio and price/quantity tick sizes for three markets. A lower maintenance margin ratio means that, theoretically, a user with a position in the Injective Exchange dApp Ecosystem will be less likely to be liquidated.
Proposal
This proposal, if approved, will update:
The BTC/USDT perp market maintenance margin ratio from 5% to 2.5%.
The WMATIC/USDC spot market quantity tick size from 0.0001 to 0.1
The WETH/USDT spot market price tick size from 0.001 to 0.01
The ATOM/USDT spot market price tick size from 0.01 to 0.001
