Update Pump IDLs and check instructions (init_user_volume_accumulator, close_user_volume_accumulator)

Message in the official channel:

Hello. We added 2 new instructions to both Pump and PumpSwap programs:

• init_user_volume_accumulator, which allows a payer to fund the user_volume_accumulator account rent-exemption lamports. payer can be any pubkey, not necessarily the user pubkey.
• close_user_volume_accumulator, which allows a signing user to close their user_volume_accumulator account and get their rent-exemption lamports back.

buy instruction in each program still requires and re-creates the user_volume_accumulator if it does not exist already. But a user can now close and claim their rent-exemption lamports from user_volume_accumulator account if they want to by using close_user_volume_accumulator.

The latest Anchor IDLs have been published at https://github.com/pump-fun/pump-public-docs/tree/main/idl, also on chain and in the latest Typescript SDK versions:

• https://www.npmjs.com/package/@pump-fun/pump-sdk?activeTab=versions
• https://www.npmjs.com/package/@pump-fun/pump-swap-sdk?activeTab=versions

No changes required. The bot and examples still work.
