Creates a one-time or recurring dutch auction swap. The auction will start at a price above the current market price and end at a price below the current market price, and will re-occur at a set interval until the maximum number of auctions is reached or the swap is cancelled.

Property	Required	Description
`type`	Yes	MUST be set to `blockIntervalDutchAuctionSwap`
`intervalId`	Yes	ID of this intent segment, can be randomly-generated.
`owner`	Yes	The address of the account to swap for.
`tokenIn`	Yes	The address of ERC-20 token to withdraw from `owner` for the swap.
`tokenOut`	Yes	The address of ERC-20 token to swap `tokenIn` for.
`tokenInAmount`	Yes	The amount of `tokenIn` to swap. Should be formatted as the amount of the smallest unit based on decimal amount of token. e.g. `10_000000` for 10 USDC (6 decimals)
`firstAuctionStartBlock`	Yes	The block number at which the first dutch auction should start.
`auctionInterval`	Yes	The number of blocks that should elapse between the end of the last auction and the start of the next auction.
`auctionDuration`	Yes	The number of blocks that each auction should (theoretically) last for.
`startPercent`	Yes	The percent above the current market price that the dutch auction should start at. Should always be `<= 100`
`endPercent`	Yes	The percent below the current market price that the dutch auction should end at. Should always be a negative value AND be `>= -100`.
`maxAuctions`	No	The maximum number of auctions that should re-occur. A value of `0` means auction will re-occur infinitely, aka until cancelled.
`twapInterval`	No	The length of time in seconds at which TWAP price-reads during the dutch auction should take place.
`twapFeePool`	No	The Uniswap v3 fee tier of the liquidity pool to read the price from. e.g. `500`, `3000`, `10000`.
