Doesn't compile with Chia 2.3.0

[Ealrann]

Hello,

The reference pool doesn't compile anymore with the last version of chia (2.3.0) because the chia.types.Announcement no longer exists.

It's used in the create_absorb_transaction method in singleton.py. I tried to simply remove the announcements, and directly pass the coin list in create_signed_transaction, but the pool claim then fail with an error ("No key for puzzle hash", I attach the log).

Any hint how to fix the singleton.py for chia 2.3.0?
