[REQ] Allow the target_puzzle_hash to be specified for self pooling to an alternative/cold wallet

[daverof]

When self-pooling, the manual plotnft claim of the 1.75 XCH can only be transferred to the current active address of the host wallet, which is of course a hot wallet.

Can you please provide a way to edit this target_puzzle_hash to specify an alternative address, to allow users to claim directly to cold wallets, to avoid having to manually transfer coins from the hot to the cold wallet every time a block is won?

	if singleton_state == SELF_POOLING:
	target_puzzle_hash = owner_puzzle_hash

Line 569 in 13ff748

owner_puzzle_hash: bytes32 = await self.service.wallet_state_manager.main_wallet.get_puzzle_hash(True)

9 weeks later and I am seeing the same behavior in 1.3.
Can this please be looked at? It's probably only a couple of lines of code to fix.
Thanks

Also, allow the delay_puzzle_hash to be specified before creating an plotnft.
