update chia_rs dependency to 0.9.0

[arvidn]

Purpose:

Bump chia_rs dependency to 0.9.0. This version adds a new field to ConsensusConstants, preparing for a soft-fork 5. This PR is not adding the code for soft-fork 5, so we just leave that field at 0 for now.

Current Behavior:

we depend on chia_rs 0.8.0

New Behavior:

we depend on chia_rs 0.9.0
