We created recently a new pallet within Pendulum to extend our current treasury pallet with the "buyout()" feature, allowing XCM asset holders to seamlessly swap a specified amount of XCM tokens for PEN tokens directly from our treasury, thereby obtaining a token for gas fees. This root transaction is setting up the parameters for the implemented buyout() feature to:

- The allowed assets: DOT, USDT, USDC, GLMR
- The maximum amount is limited by the BuyoutLimit - Max - 1 PEN/24h

Schedule the currently externally-proposed majority-carries referendum to be tabled
immediately. If there is no externally-proposed referendum currently, or if there is one
but it is not a majority-carries referendum then it fails.

The dispatch of this call must be `FastTrackOrigin`.

- `proposal_hash`: The hash of the current external proposal.
- `voting_period`: The period that is allowed for voting on this proposal. Increased to
	Must be always greater than zero.
	For `FastTrackOrigin` must be equal or greater than `FastTrackVotingPeriod`.
- `delay`: The number of block after voting has ended in approval and this should be
  enacted. This doesn't have a minimum amount.

Emits `Started`.

Weight: `O(1)`

Send a batch of dispatch calls and atomically execute them.
The whole transaction will rollback and fail if any of the calls failed.

May be called from any origin except `None`.

- `calls`: The calls to be dispatched from the same origin. The number of call must not
  exceed the constant: `batched_calls_limit` (available in constant metadata).

If origin is root then the calls are dispatched without checking origin filter. (This
includes bypassing `frame_system::Config::BaseCallFilter`).

## Complexity
- O(C) where C is the number of calls to be batched.

- **Problem Statement:** Implementing the "buyout()" feature in the treasury pallet to enable XCM asset holders to swap XCM tokens for PEN tokens efficiently.
- **Significance:** Enhancing the treasury pallet functionality by allowing seamless token swaps for XCM holders.
- **Proposed Solution:** Introducing the "buyout()" feature with specified assets and a maximum limit of 1 PEN per 24 hours.
- **Expected Outcomes:** Improved user experience and increased efficiency in token swaps within the Pendulum ecosystem.
